I think it’s too soon to worry about this. I don’t see a reason to harass people who maintain code based that were just recently migrated.
Yes, I also think that it is too early to deprecate it just now. Python 2 is not completely dead yet. But I would happy to know some estimated terms.
BTW, BytesWarning and the -b option also are only needed for programs ported from Python 2. This great feature helps to catch some porting errors, but makes the pure Python 3 code more cumbersome and less efficient. For example, you can't use just `name[0] in ('.', b'.')`, you have to perform the `isinstance(name, bytes)` check first, and you can't use the same cache for string and bytes keys (you have to use `(type(key), key)` as a key).
