How many more posts you think we can get by going back and forth like this?

Why do only the one, when you could do both?
One spell and not both? Because 16 Int starting and a +3 stat book was "excessive" and I didn't want to offend.
I find rounded characters -- characters who are more than their class, and a bunch of numbers to optimise that class -- to be preferable in all but silly hack-fest oneshot games (which, ofc, have their own brand of fun).
*I* find that characters that have all their stat allocations in one stat can still be rounded by feat selection, skill selection, prestige class selection (or lack there of), magical item selection, and in this case spell selection and daily spell preparation.
Having a 30 on your character sheet does not mean you cease to be able to roleplay or are incapable of choosing feats such as, say weapon proficiency: longsword.
It adds only to their UberWizardNess(tm). It doesn't make them that much different from the NEXT 2D cardboard-cutout wizard who's done the same exact thing, now, does it?
Now that's plain silly. It adds skill points so you can deviate with things like armorsmith, diplomacy, alchemy, or profession tailor if you like. It also allows you more flexibility in your chosen profession, in this case casting "spells, spells, moe spells".

That it raises your spell DC's is just gravy.
That's still 2D. "Spells, spells, moe spells" is about as 2D a wizard as you can make (you can go 1D if you wish, with all the exact same spells, but that's a different issue). The point is, the character isn't anything BUT a spell-thrower.
WHAT?! When was the last time you played a wizard?

A wizard with access to more spells (higher INT=better spellcraft for scribing) and more spell slots (bonus slots to prepare spells that couldn't normally be afforded) and the ability to scribe formerly said greater library spells makes a wizard anything but "just a spell-thrower".
With charisma boosting spells he can be a diplomat or spy.
With invisibility and flight he can be an infiltrator or cat burgler.
With mage armor, shield, stoneskin, globe of invulnerability, and tenser's transformation he can be a front line tank.
With summon monster ("Walk down that hallway.") and knock he can be a trap monkey or locksmith.
With rope trick or secure shelter or magnificent mansion he can be a night watchman.
With see invisibility, glitter dust, and dispel magic he can be a mage killer.
With phantasmal killer and finger of death he can be a rogue killer.
With wall of force or charm person he can be a fighter killer.
(We don't want to kill clerics, so we'll maze them. Best not to offend the gods.)
With stat buffing spells and meta magic we can double and triple those piddly level up stat bonuses that apparently make us two dimensional.
And with high intelligence we can do all of these on the same day every day.
Tell me how that's now rounded?
By all that logic, having a Wizard take the feat, "Martial weapon proficiency: Longsword" would also be silly ... yet, Gandalf, quintessential archetype of the D&D wizard, wielded Orcrist, a magical elven longsword, with proficiency.
I thought Thorin had Orcrist and Gandalf had the Foehammer (whichever one that one was...

). In either case, a wizard could take whatever feats he wanted. I never said otherwise. I just think that putting all your stat increases into your spellcasting stat is a wise choice for a wizard.
Sometimes deviating from "the path of assured min/max goodness" is better ... like when it produces a character who is not a 2D cardboard-cutout mockery of role playing.
As I said, a 30 intelligence does not mean you stop role playing.

But I might also add, that with the way 3e is designed, sometimes diversifying your abilities all over the place only makes you good enough to almost succeed at everything you try. The game's mechanics and CR system assume that at X level you have Y capabilities. If you diverged off your expected course too extremely, you may not fill those capabilities, and what should be a simple challenge could cost adventurer lives. This isn't a necessarily bad thing, but neither is your assertion that having high stats makes a two dimensional cardboard-cutout mockery of role playing.
Sometimes, particularly in the case of single classed spellcasters, focusing on your strengths is wiser than diversifying to different fields that can be done better by other party members.
This doesn't mean that you are a one trick pony (ESPECIALLY not with a wizard's repetoire), it means you require, and in fact
encourage roleplay.
