Given that it is deployed and working well but not well understood,
this seems like an excellent candidate for an Experimental RFC, which
is what the expired draft here
https://www.ietf.org/archive/id/draft-ietf-babel-rtt-extension-00.txt
is targeted for. Presumably the experiment would be to try variations
in different deployments.

If even experimental is considered too ambitious, it could be just an
informational document to make a record of the known good deployment.
(Either experimental or informational would work as the basis to
allocate the required code point.)

Thanks,
Donald
