Yes, that was pretty much my reasoning. To quote the `prog-mode`
docstring: "Major mode for editing programming language source code."
Unless there's some XSLT equivalent for YAML, I do not see it being
programming language source code at all.
Perhaps "programming language" is intended to mean that a given file is "legal" is decidable (which lets TeX off the hook).
YAML has been argued to be several things (configuration,
serialization, text) and having to choose one in particular cannot work
out in a satisfying way unless it's about a very basic property not
based on opinion
The YAML spec is insistent that it is a data serialization format.
