be had about whether YAML is a programming language and one whether
yaml-ts-mode inheriting from prog mode just makes it nicer in practice.

I haven't seen anyone argue that YAML is a programming language per se, and
I don't believe that either. However, to me there is a prevalent feeling
that it would be nice and consistent with the other elpa shipped modes of
similar languages inherit from prog mod.

As to me calling yaml-mode inheriting from text-mode arbitrary; I mean that
in the sense that it was not discussed. It was done with a reason and as a
conscious choice, but it was a singular maintainer's choice in a non-GNU
elpa package.
