Matt / Olli,

I'm not aware of anything that could be enabled by non-apex ZONEMD records. My preference would be to forbid non-apex ZONEMD records.

I guess my concern was just that it means implementors need to check for this and treat the RR type somewhat specially, as they do for SOA and maybe a couple other RR types.
