Debian allows multiple versions.  There seems to be a metapackage that
depends on the "default version" (currently 2.6) and provides a
/usr/bin/python symlink to it, but other versions can be installed as
well.  If the administrator wants to change the "default", I think
they'd need to build a locally modified version of the metapackage.

I assume that they have reasons for doing it that way instead of with
/etc/alternatives.
