And we can talk about if "universal" is really a good goal either.
Taking a bit of a guess in the dark, an SDK with support for all the fun

support for all the fun stuff found on some other ref board too.

I tend to think of these exports as being very board specific, but that
doesn't quite flow with how others think of this stuff, today.
