A far easier approach is for any developer to feel free to treat these
RRtypes as unknown RRtypes.
I'm not sure I understand the distinction you're making here?
What you said sounds similar to what the document proposes, so
perhaps the document is unclear, or perhaps I've misunderstood you.
I am proposing that we don't need a document, nor changes to the IANA registry:
just treat whatever RRtypes you as a developer feel are no longer used as
unknown types and move on.
The problem with this approach is that it requires a developer to go
through all of these RRtypes and read the specifications and figure out
what each is, then try to figure out if it is something that is commonly
in use. Probably that means going through various on-line manuals from
proprietary implementations, as well as scanning through documentation
and source of popular open source libraries and servers.
It seems like a lot of time could be saved by being able to look at the
IANA list and discover that a given RRtype is deprecated.
We have a lot tribal knowledge about how to implement DNS. Reducing that
amount seems like a good thing.
