The flip side of the argument is that if you have compiled stuff in
current, you have the capabilty to do it again, so if the versions
were bumped early enough, you only influence the apps that you have
compiled, but keep on making it possible to run current and still
use apps that was compiled for older versions of FreeBSD. So you
make if possble for more people to run current even on there desktops
and get a lot more testing milage out of current.

I vote for bumping the version of a lib the first time it goes 
incompatable ... actually just before that so that you don't get
incompatable libs with the same number.

And yes I do run -current on my home desktop too and no the FreeBSD
foundation do not have a diablo package for current. :-/
