But during package installation, this information will be written
into a .PTH file somewhere along the python path...

but if you can't uninstall an older package from the system... then
how can you install the newer version with all the new information..

this leaves the user quite stuck...

That's my point....

Having a system where new packages can be deinstalled and old packages
cannot be deinstalled will be totally confusing for users. 

It will drive most users crazy - if you think about it.

If you have a deinstallation facility, then it must work for new
packages as well as old. Otherwise, imho there's just no point.
