This sounds like a great transition plan indeed.
Then we could have a warning for now, that would be transformed in an
error in a year,
and migrate to this new setup that detects wrongful combinations,
without forcefully breaking things in the meantime.

Robert, also, in the manual you should advertise #+asdf3.1
non-propagating-operation, or something, because it won't exist
earlier, and we probably want code to keep running with asdf 3.0 until
every implementation has upgraded to 3.1.
