I also sometimes miss CallerBlocks policy, which:
  - throws RejectedExecutionException when pool is shutting down
  - blocks until executor accepts the task, and returns after successful submit

This is helpful when I specifically don't want submitter to execute
tasks slated to be executed in the threadpool (i.e. CallerRuns is not
something I want). It was especially problematic when the task at hand
is rather heavy, and by the time submitter is done executing the task,
threadpool is had been long idle already, because submitter is, well,
