You are right that many of the prefixes can be handled by the same code:

In almost twenty years of using Python, I've not seen capital string prefixes in real code, ever. Sounds like a great candidate for deprecation?
It's not like migrating would be hard: a replace is enough to fix the rare projects doing that. And even if they missed the warning, it's a syntax error anyway, so you will get the error as soon as you try to run the program, not at a later point at runtime.
What about doing a poll, then suggests a warning on 3.8, removed in 4.0 ?
Also, Python is case-sensitive elsewhere, so why not here too?
OTOH, it's not like it's causing a problem.
