Well, my (possibly wrong) vision is that one of two scenarios are most probable:
- essentially single-user machine, so the user-admin will probably install
system-wide TL2010 too
- multi-user machine, like in a university network, where the user is hopefully
unlikely to ever want to install something like TL on his account.

But of course those are not the only possible scenarios.

It seems to me the installer is already doing that. From Phil's original message:

Warning: conflicting [pdf]tex program found on the system path in [...]
