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.
