It's also true that I've seen greedy casters go for the 18 in a 25 PB scheme, with some terribly boring character like--8 11 14 18 8 8. It's easier to do that for a cohort, where you typically don't care as much for the charisma because she's on the sidelines or the strength if the PC can carry spare stuff.
I totally agree that it is easier for a cohort. That's why I would like to limit it. As things currently stand, I do not think it is more likely for a cohort wizard to have an 18 intelligence than it is for a PC wizard to have an 18 intelligence. If we give cohorts 28 or 30 point buy, then I think it becomes more likely for the cohort to have 18 intelligence. If a PC wants to be really focused, I think they should be better at the focus than an equal level cohort.

Since they could make a cohort with an 18 anyway in 25 PB, I don't see why we should limit them in 30 PB. They'll wind up with something like 8 14 14 18 10 8 or 8 12 16 18 8 8.
But, as you've argued, the character will be less survivable. I'm sort of confused by this. Is the point of increasing the point buy to make cohorts more survivable, or is it to make them more flavorful, or is it to make them more powerful, or is it to make them all three? With 25 point buy, you can build a wizard with decent survivability, and decent flavor: 8 points to casting stat, 6 points to Dex, 6 points to Con, and 5 points to spend on the other 3 stats - enough to make one relatively high, or to make all average. If you want a more unusual array, only put 6 points in the casting stat.
If the purpose of increasing point buy is to take a character like:
Str 8, Dex 14, Con 14, Int 15, Wis 8, Cha 13
and make it
Str 8, Dex 14, Con 14, Int 17, Wis 8, Cha 13
then I don't think we should increase the point buy.
However, if the purpose of increasing the point buy is to take the same character:
Str 8, Dex 14, Con 14, Int 15, Wis 8, Cha 13
and make it
Str 8, Dex 14, Con 16, Int 15, Wis 8, Cha 14
in order to increase survivability and allow fleshing out the character a bit more, then I am in favor of it.

But what if one of the other PCs is a really low level character of exactly the same class as the cohort? Well then the GM can choose not to allow the cohort that time--the guy hiring at the inn could even say "Hey, we don't need two fledgling Wizards on this adventure".
I think it makes sense to avoid that option whenever possible, and I think it is workable to have a cohort and a lower level character of the same class in the same adventure. Why would Batman say, "Robin, you sit this one out so that I can go on an adventure with this entirely new person I just met." It can work, but there are better options in my opinion.

I think the overspecialised cohort is actually better for the spotlight problem, particularly the cohort that spends 100% of points on casting stat and then Con/Dex for survival. Your opinion may vary, of course.
This I do disagree with. The extra stat points in "unimportant" attributes don't really contribute much spotlight time in my opinion.
