It's not necessary to provide a full P.o.C but a small demonstration of
the kind of ww_mutex API you would prefer would be helpful. Seeing a few
sample Rust use-cases (especially in comparison to existing C
implementations) would give a clearer picture for me.

At the moment, the implementation is just a wrapper ([1]) around the C
ww_mutex with no additional functionality, mostly because we don't have
a solid consensus on the API design yet (we had some ideas about Tuple
based approach, but seems like that isn't going to be useful for most
of the ww_mutex users).
