Are you sure it gets reset to root? I've been on since the first public beta, quickly fixed the homebrew problem, and haven't had any permission issues since. Admittedly I can't say if normal updates will behave different from the beta ones.

I can't be sure obviously, but if it's done once by the installer, there's no reason to assume it won't ever do it again. So in the worst case, you'll have to re-chown every time you install an update.

Or you don't chown and run brew as root.
