I agree that we could explain it as "man with fancy on top". But it
makes me wonder: why is this Git's responsibility to do the fancy at
all?

I.e., if you want colorized manpages, why don't you configure man to do
so? Sure, it's a bit of a pain to do so since it involves setting a
bunch of obscure environment variables. But if that's what you want,
wouldn't you want it for all manpages, whether you ran "git help log" or
"man git-log" or "man ls"?

This seems like a "man" feature and not a "git" feature. And arguably
some of it is really a "less" feature (it is trying to set "standout"
mode for its prompt, so configuring "so" and "se" termcap entries is
just reinterpreting that. If you like, wouldn't you want it on for all
"less" invocations?).
