I don't have an opinion one way or the other regarding bytearray, but even if you deprecated it rather than dropping it, couldn't you just add the surrogate support for the Unicode path and leave the bytecode path with the legacy behaviour?

Yes, we can do everything. But does it really have a sense? No Python function using filenames return a bytearray object. Example: os.listdir() and os.walk() result type is bytes or str.

Changing PyUnicode_FSConverter() is trivial, but the problem is in the function calling PyUnicode_FSConverter(). The caller have to support byte and bytearray. Antoine proposed to convert bytearray to bytes to ensure that PyUnicode_FSConverter() result is a bytes object. But in this case, we still need also to fix ntpath, ,posixpath and macpath modules to support bytearray.
