Not exactly.

First of all, it's the same situation as Markdown (see the text/markdown 
discussion over time on the apps-discuss mailing list).

The most important hurdle has been passed: some people actually *want* 
text/yaml.

The second hurdle has also (likely) been passed: people are actually 
using text/yaml for YAML stuff. This turns out to be more useful than 
the registration itself. Deploy first, register later. ;-)

The next hurdle is overcoming developer laziness, since it requires some 
modicum of effort to do the registration. Sounds like we have a willing 
victim...er...volunteer. ;-)

Getting text/yaml just requires an Informational independent-stream or 
IETF stream RFC. First write an Internet-Draft. The Internet-Draft can 
reference the yaml.org specification, without changing control over the 
specification to the IETF. Then submit the draft to the dispatch mailing 
list. (Maybe also a couple of other mailing lists, for places in IETF 
that use YAML.)

Depending on the outcome of the discussion, either the IETF will take it 
up, or not. If they do, then the media type registration will be 
published with IETF Consensus (see text/markdown). If not, then it can 
still be published an the independent stream by submitting it to the 
Independent Submissions Editor (see image/bmp, aka 
draft-seantek-windows-image) 
<https://www.rfc-editor.org/about/independent/>.


I have not tried to register a structured syntax suffix before. 
Superficially, the process appears to be simpler, as it only needs 
Expert Review. For that, just follow what RFC 6838 Section 6 says.

Best of luck!
