I don't have anything precise in mind, I admit. All I can say is that
it needs to be extensible, in case we need to export more register
values in the future.

No. We can have a universal exit sequence, but enter sequences are
per-chip (or actually per chip family). That's even one part of the
device identification (lets us differentiate between two chips with the
same device ID register value.)
