Hmm, erikun has gotten me to rethink this a bit, and actually this does seem more reasonable. Agreed after all.
I believe I'm confident enough in this to now register agreement.
Much preferred to the original version; agreed.
Somehow I seem to have missed this on my previous run-through, but it is quite clearly a good change, so agreed.
I do not presently know of any legitimate (non-abusive) use for 030A's reading, so I'm changing my previous abstention to disagree with that and agree with 030B.
This seems ... hmm. Maybe a bit unnecessary? Generally the ways of gaining double Cha to saves, for example, require a lot of hoop-jumping, and while they are indeed more powerful, I don't necessarily see them as brokenly so. I could certainly see the point of houseruling it one way or another, but I'm not really sure there's any clear dictate from common sense to decide it.
As mentioned previously, there are cases where the bonuses implicitly stack by their nature (Con to natural armor, Con to armor), cases where they explicitly do not stack (Monk/Ninja AC bonus), but no cases I'm aware of where they explicitly stack. However, the default would seem to be to treat them as an untyped bonus, which would stack.
Anyway, upshot is that this seems a little dubious to me right now, both in scope and in conclusion, so I think I have to disagree pending further discussion.

Also a largely unrelated linguistic nitpick: the "yay" sound you make when formally agreeing with something is actually written out as "yea". No more typos please.
