You'd be surprised how many tools and programs are using Python these days.

Certainly not. I wrote or helped to write a lot of them myself. :-)

You can easily break important user programs by installing a package with --user.

Under root? Probably. Then don't do that -- or do not allow system Python to import user-specific site-packages (i.e., distinguish system Python from normal Python running under user root). But for a non-root user user-specific site-packages is quite a convenient thing. Please don't remove it.
