Planning to close in favor of gh-9413. From #78913 (comment):

I'm specifically worried by the _windll() example in PR 53663, in which a non-RFC 4122 conforming UUID is created, leading to the addition of the new "strict" keyword argument so that we can disable the new check in __init__ in this case. There's a good chance that there are other such scenarios of which we're simply not yet aware.

In light of this, returning None for UUID.version, as in PR 53659, actually seems like a very reasonable solution.
