I agree with Nick; this is really a minor issue and we can resolve it here in the tracker. I missed the place in the PEP where it said that the option should be checked, since it mentions changes to the installers twice, and in "implementation strategy", it doesn't mention a default.

I'd prefer if uninstall was "symmetric" to install, i.e. if I need to run a command on install (rather than deploying files directly), then I also should run a reverse command on uninstall.
