That could change how good it is or isn't for spellcasters.

But, all in all, I don't think it'd be much abusable. Some, yeah maybe, in that you can make a build that avoids making attacks. But the boost from small size isn't itself game-breaking; even the stuff it could boost awesomely sounds fair to be awesome out without being really overpowered. Even adding to an optimized spellcaster wouldn't be a major boost (since what they already have, and it'd presumably mean not picking a race that boosts their spellcasting stat.)
It would take digging through years of threads, including ones involved he who shall never be summoned, but yes, by RAW, spells that do "bad things" to anyone is considered an attack.
