Given the lack of comment for or against, I'm going to follow this
route. That and my oodles of free time given the current worldwide
virus situation, I think I should be able to work on something.

I'm not intending to have anything in time for 5.32, it being a bit
late now, but my hope is to have something that looks merge-ready early
in the round for 5.33.x so we'll have plenty of time to bring it into
blead and test it out, before it hits 5.34.
