Following up on this exact use-case, due to my text-mode hooks, using 
yaml-ts-mode many times ended up with causing invalid YAML or breaking 
existing YAML-files.

I was pretty sure yaml-ts-mode itself was buggy and actually started 
using fundamental-mode to edit yaml-files instead, until I realized what 
was going on.

== Yes. The user-experience was literally that bad. ==

Lots of people are going to have lots of problems and breakage when 
using yaml-ts-mode as it is today, deriving from text-mode.

I plea from the bottom of my heart that we allow a change to prog-mode.
