Why was the keyword argument 'encoding' removed from json.loads() in Python 3.9?

The official docs of the json package state:

json.loads(s, *, cls=None, object_hook=None, parse_float=None, parse_int=None, parse_constant=None, object_pairs_hook=None, **kw)¶

Changed in version 3.6: s can now be of type bytes or bytearray. The input encoding should be UTF-8, UTF-16 or UTF-32.

Changed in version 3.9: The keyword argument encoding has been removed.

What was the purpose of the 'encoding' keyword prior to Python 3.9? Why was the encoding keyword removed? Is json.loads() (3.9+) capable of automatically detecting bytes and bytearray input encoding from UTF-8, UTF-16 and UTF-32?

Yes -- if you look at the json package source code, json.loads() calls detect_encoding(), which, appropriately, detects input encoding. Check out the code for detect_encoding() here.
