As others have said, I think `is_segwit` should match all segwit
versions. Pavol also sorta answered your "widely used name" question
though he didn't draw attention to it -- segwit v0 outputs are called
"p2wsh" or "p2wpkh".

But I don't know any term that covers "p2wsh or p2wpkh but not p2tr".
Other than "segwit_v0", which we are currently using, and which I agree
is a bit of a mouthful.
