Thanks, this looks pretty good overall. I just had a couple of nits and a larger concern about the escapes in byte strings.

I think this check applies to byte strings too. This is the thread that prompted these changes: #14679 (comment), and it looks like the escape there also works for byte strings:
>>> import re
>>> re.sub(b"foo", rb"\g<0>bar", b"foobar")
b'foobarbar'so I don't think we can restrict this to the string literal case.

I see what you mean - I updated the logic to handle both str and bytes literals for the replacement argument by using match on the resolved literal.

Thank you! I found a few more very small nits, but this is good to go otherwise.
