Seems reasonable.

This approach would appear to rule out the option of setting a work
thread's state (scheduling policy, scheduling priority, uid, etc) to
anything other than some default.

I guess that's unlikely to be a problem if we haven't yet had a need to
do that, but I'd be a bit surprised to discover that nobody has done
that sort of thing yet?  Nobody has niced up their workqueue threads?
