+1 from me. And maybe explicitly state that installing multiple
versions of a distribution is not supported. Although this opens a
somewhat larger can of worms, in that you can install different
versions in separate directories - say in system and user
site-packages - and that has subtle issues but is technically not
rejected at the moment. So maybe restrict it to stating that
installing multiple versions of a distribution *in the same directory*
is not supported and duck the bigger issue for now.
