Do you make clerics research new spells not in the PHB?

If I wanted to actively seek out new divine spells, I'd be playing an archivist.

Each god has his own spell list and each cleric's faith is determined. Based on these two you come up with a final list of spells that a specific cleric can select from. If a new spell comes out or that I develop for my game and I feel the a specific cleric in question has already proven himself worthy, then by all means they see the divine light. However, I do not assume anything is simply given as you would have it because you feel you have nothing to prove.

Well, this makes some sense, remaking the cleric "spheres" of thematic spells. I'm OK with this kind of restriction, it's the "PHB spells are normal, everything else is weird and unknown and must be researched" attitude I don't understand.

The idea that every spell is open for selection is crazy. Sorcerers have their bloodline which almost creates the base spells, as does their moral and ethical swing but they can also select a bit longer and expensive route using a scroll as the base. Wizards base is determine by where exactly they are in the world at that given moment to create the baseline and even then there is a fair amount of research involved.

Seriously? Where the wizard is at the moment he levels decides what spells he can add? That seems... super-annoying. "Crap, I wanted Disintegrate, but only Arcane Sight's available! I knew I shouldn't have made that trip to my mother's!"

I can understand some kind of restriction on the divine casters, but wizard (and especially sorcerer, holy crap dude) spell selection is restrictive and expensive enough already. The free spell choice per level hardly seems overpowering.

EDIT: Err, well, no more overpowering than any 3.5 full caster. Granted, they're all pretty OP as is, but that's another issue...
