Or by writing a Python script and innocently giving it the same name as 
a system module.

On the tutor@ and python-list@ mailing lists, it is very frequent for 
users to accidently break Python by accidently shadowing an installed 
module, e.g. installing xlrd and then calling their own script 
"xlrd.py". But I've never come across somebody breaking anything by 
installing a package with --user.

I presume it must happen, but I would be surprised if it happens often 
enough to justify removing what is otherwise a useful piece of 
functionality.
