My $0.02 on the size issue:
I think the onus should be on whoever is publishing a zone with a
ZONEMD to provide guidance on what to do if a failure occurs.
Similarly, publishers should be sensible on whether to include a
ZONEMD based on total size and rate of change.
Then there should be some sort of signalling mechanism WITHIN DNS that
allows a consumer to figure out what to do when the failure occurs - if
that is going to be a per-zone case. Perhaps a field in ZONEMD?
What you're suggesting somewhat has the conclusion that this will never
be useful in general purpose zones, because the consumers of those zones
would have to have a back channel path to find out the guidance for
potentially large numbers of zones.
