Presumably there are companion userspace tools for DAMON.  Are they
available?  Is there a plan to release and maintain these?

Yes, the userspace tool[1] is available, released under GPLv2, and actively
being maintained.  I am also planning to implement another basic user interface
in perf[2].  Also, the basic test suite for DAMON is available under GPLv2[3].
