Depends on whether you talk about the provisioning side, or the client
side. On the client side (which query for the records) and the "plain"
servers, I claim the adoption is not bad at all. When looking at
provisioning systems, things are worse.
BUT, one have to remember that:
- On the receiving side, the application have to be updated to use
whatever algorithm is specified by the MARID-protocol-whatever-thing.
As part of this upgrade you can always query for whatever DNS record
you want. The software have to be updated anyway.
- On the sending side, there is a problem because the DNS people in an
organisation is not the same as the people managing mail, and there is
not many argument(s) for the DNS people to upgrade/change their
provisioning system due to some mail issues. On the other hand, you
need to change the provisioning and other things anyway if you want to
inject MARID stuff in records, regardless of the type of the RR.
Finally, if one run a DNS server which can not by any means handle
unknown RRs (even via the provisioning, for example by use of **VERY**
old version of BIND) you should most certainly upgrade your server
anyway. DNSSEC etc is coming, with many many new RRs. MARID is not the
only wg which is introducing (as I hope) new RR types.
