Your is exactly an example that - as it is in UA - the Domain Wizard is simply unfair to the core Wizard. You yourself noticed it and put it back to be a fair alternative by adding a prerequisite feat (which is also quite a good idea IMHO, although I guess that every non-spec Wiz would take it).
Actually, the Wizard in my new campaign declined the option; he's "just" a regular PH non-Specialist wizard.
My decision to use a Feat was based on the way it was implemented in the Forgotten Realms. Two of the Regional Feats there pretty much do the same thing. Since I did want to keep the regular PH non-Specialist as a viable option, I chose to do it the same way. If I had not wanted to go the Feat route, I would simply have made all non-Specialists Domain Wizards.

UA may explicitly say "you this variant either as a side-alternative or as a replacement"; but if the variant cannot be fair as a side-alternative, that's the design mistake (at least in saying that it could be used together with the core class).
Well, it is up to the DM to decide whether the variant can or cannot be used side-by-side with the core class in his/her campaign. If a DM wants to limit Domain Wizards, for example, to coming from one specific land, characters from other lands must be either PH specialists or "standard" non-specialists.
I use many of the Class variants in UA to help give different lands a different feel. The Whirling Frenzy rage variant is found among the celtic-flavored barbarians of my world. I use the Totem Barbarians in three different areas, but which Totems are available in each area are different.

We really didn't need UA to emphasize this, since it has been the same for every accessory book (and with core books as well since almost everyone has rule0 some spells or items). The real difference introduced with UA - as you also point out - is that some of the rules variants are incompatible with each other from the start. What annoys me is NOT that RULES variants may be incompatible, but for some reason it annoys me that one single CHARACTER variant is. Why? Perhaps because it affect only 1 character, while a rule variant affects everyone.
Sadly, even though all such supplements do indeed say "Ask the DM first", there are a large number of players who manage to somehow not see that until you point it out to them,

I am not saying that the core wizard is weak, and neither that the domain wizard is strong. I just don't understand why this special treatment for the wizard class. If the reason to put the DW in UA was to provide a more powerful variant, why not having also for the others?
Other variants, like letting Clerics spontaneously trade their prepared spells for a Domain spell instead of a Cure, also do not work well side-by-side with the standard class.
The Battle Sorcerer is another. The loss of 1 spell each level (both known and usable per day) to a minimum of 1 is arguably a small price to pay for d8 HD, Cleric BAB, Proficiency in 1 Martial Weapon, and the ability to wear Light armor without Arcane Spell Failure. Some would say it is clearly a "better" Sorcerer, and outmodes the standard PH Sorcerer.
My point is that the Domain Wizard is not the only variant that does not co-exist well with its standard version; it is just the most obvious one. However, a lot still depends on how the DM chooses to bring it into the campaign.
