As per the other reply, that sounds good -- it doesn't make sense to merge one
without the other but it sounds like maybe they can both be ready in time for
3.9.

There's no hurry, 3.10 is ok as a target as long as it's taking place. The main
reason for why I was asking was that there was still some legacy board file
updates posted, and that I hadn't seen much patches lately that made it obvious
that there was an effort in that direction. 3.10 sounds like a good target.

Thanks, you too.
