------------------------------------------------+------------------------
`python-memcached` is not maintained anymore (see
[https://github.com/linsomniac/python-memcached/issues/95 python-
memcached#95]) and it makes difficulties in fixing some issues (e.g.
#29867). Moreover we added a cache backend for `pymemcache` (#29887) so we
have a good builtin alternative.

I think it's time to deprecate the
`django.core.cache.backends.memcached.MemcachedCache` backend in Django
3.2 and remove it in Django 4.1.

Comment:

I'm going to accept this. We can give it a few weeks to see if there's any
objections/movement on python-memcached.
