That's a good start, at least.

It's not as far-fetched as you might think - if "vv" means "more
verbose", and "qq" means "more quiet", then "VV" means "more version
info". It's a form of word doubling for emphasis, a tradition that
dates back at least as far as ancient Hebrew, and has some currency in
English. And if -VV has no other meaning, it's not going to hurt to
accept it as an alias for -Vv, right? Remember, this option isn't only
for the expert - it's also for the novice, who might be typing at the
dictation of someone else ("can you tell me what python -vV says,
please? -- no, that's one capital V and one small v -- no no, not both
capital, just one"). But if it can't be done, so be it. At least with
them being independent flags, the order doesn't matter.

Sure, I guess. Not sure what -Vvv would mean, but okay. The same could
easily be done with -VVV though, just by making -V a counted option.
Logic could simply be:
# Count verbosity based on -v and/or -V
Version += verbose
if Version >= 3:
print("info for -Vvv")
if Version >= 2:
if Version == 1:
# subsumed into the above
