More basically, could someone point me to a description of the problem
that '-delete' is intended to solve? I found:
Are they on-topic? Was there any consensus that -delete addresses the
problem the best way? (Sorry if I missed it.)

As Mouse said (approximately), it would be interesting to consider the
problem in terms of what find(1) would have to pass to a filter that could
do what -delete is meant for. We know how to pass handles between
processes. Might it be useful to make find(1) do that instead? Various
handle-accepting filters could do different things with them, unlinking
being only one possibility.
