The development version (7.3dev) already has schema support. It's not
necessarily to be recommended but unless you want near certainty there aren't
problems lurking in 7.3 that weren't in 7.2.1 I would suggest you obtain the
7.3dev and try it out.

I'm not sure what trouble there could be. I've not heard of people using large
numbers of databases but I don't see that it would be a problem. Unless someone
else has some information to impart on this I'd suggest you try it out, not
necessarily infront of the classes.
I would also suggest that before you start you obtain 7.2.1, if not the 7.3dev
for schema support, and use that.
