For standards version numbers, we tend to set this to a 'date' more or less, so
something like `20230119`. I wonder if there is value to making THAT how we do
this here too?

Why is this =="Clang" specific? Since you've added the Version to the
spelling, I'd anticipate us to just be able to grab it for the current
spelling. I wouldn't want an individual spelling here to override it,
particularly since with this change Clang could potentially override the
standards version.
