I've been sporadically trying to get something like this done for AGES. There was even a forum made, but without official endorsement it got like 5 members and died within days.
If you were to offer a tested contrib to the LW code base, Trike might agree to add it on a trial basis, provided EY&Co approve. Not sure what their policies are.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
(I plan to make these threads from now on. Downvote if you disapprove. If I miss one, feel free to do it yourself.)
