If you look through the octoDNS providers there's a number of cases where extra info is stored for "dynamic" records. The metadata is often things like the pool name or rule number. In other cases it's details about the health check config/version. The extra info is sometimes stored into a "notes" field, other times it's encoded into the ID or similar.

It's true that nothing extra is needed for simple/standard records, but once you start doing GeoDNS, failover, health check, etc. it's required.

In all cases thus far we've been able to find a way to store/indicate whatever we need.
