It's because it's a two-way street: Linux distributions support
OpenStack (mainly by packaging all OpenStack requirements) and OpenStack
supports distributions (mainly by supporting the versions of Python they
ship). Depending on what you actually mean by "support", the list changes.

That's the list of distributions that have install instructions in our
doc. There are distributions out there packaging OpenStack which did not
contribute this documentation (Gentoo comes to mind).

That's systems we run our own CI tests on and we pledge not to break.
That said we run those tests from Python source code, not from
distribution packages, so that pledge is obviously limited.

If you are after "the list of distributions with a well-known packaging
of OpenStack" then yes, the union of those two lists + Gentoo sounds
accurate to me.
