I'll try to contact the author and see what comes up.  Supposing the
userlock module is re-licensed (or a suitable replacement is contributed
and accepted), is there any merit to:

Promoting the user lock wrappers out of contrib (plus fleshing them out
a bit)?
Adjusting the pg_locks view to return the user lock specific information
(or, as Alvaro suggested, to add a new view)?
A general documentation update wrt user locks?
