Is this getting any traction, and if not, why not?
No.
1. Proposed by Microsoft to solve problems with SenderID. Tied

2. Replaces an SPF check of Mail From with a new arbitrary identity that

only be verified by accepting the body of the message.
If you like Submitter, just do Sender ID. It'll do a good job of
ensuring no
one abuses your domain name in resent-sender.

Too bad. The basic idea is straightforward and has advantages in both

During the IETF MARID working group I suggested that and Microsoft declined
to separate it from PRA.
