we seem to have dropped the ball on this one due to lack of bandwidth
with the whirlwind of last year's work. I actually like the basic
idea you were proposing, as long as we use the post_execute hook to do
the registration rather than adding a hard-coded check on sys.modules
to every single execution.
If wrapped into a single flag that can be set by users who want this
capability, as you propose, I think it could be very useful.
If you're still interested, feel free to put up a PR with an
implementation and we can go ahead with review.
