PEP 594: uuencode codec and binascii functions apparently not properly deprecated or documented as such

As referred to in #92611 , PEP 594 (PEP-594) states that the uuencode/decode-related functions in the binascii module, as well as the uu codec will be deprecated in Python 3.11 and removed in Python 3.13:

The uu module provides uuencode format, an old binary encoding format for email from 1980. The uu format has been replaced by MIME. The uu codec is provided by the binascii module. There’s also encodings/uu_codec.py which is a codec for the same encoding; it should also be deprecated.

However, as far as I can tell, those deprecations are neither implemented with warnings in uu_codec.py or binascii (although I'm not sure what a deprecation warning at the C level that should appear at the Python level is actually supposed to look like) nor are they documented in the respective uu codec or binascii documentation sections.

Is this intentional. If not, shouldn't we get these in for 3.11?
