I guess they will have to support both architectures for as long as 8-bits is useful and viable and that will be a long time.
It follows then that there will be more work to do and presumably the same number of guys to do it, that could be an issue. Maybe they could do with a new 32-bit "team" to port the official code/libraries as they are created and/or modified.
A couple of people have suggested they are willing to help, as would I be.
