If someone sees that

somevar[3] == b'd' is true, and that somevar[3] == 100 is also true, they might expect to be able to do things like n = b'd' + 1 and get 101... or maybe b'e'... Maybe they should :) But why wouldn't "they" expect b'de' + 1 to work as well in this case? If a 1-byte bytes is equivalent to an integer, why not an arbitrary one as well? The result of this must obviously be b"de1".

To clarify my original one-liner: if bytes objects (but only one-char bytes objects) equal integers, you should rightly expect to treat them as integers.

This is obviously not desirable from a strong-typing POV.
