In the snippet I posted, I used the variable font-lock-mode to test
whether font-lock is enabled. Its documentation states:
Non-nil if Font-Lock mode is enabled.
Is this documentation valid? If not, could you please adapt it, or -
alternatively - make the implementation match the description?

Personally, I suspect that adding this would not cover all cases. I get
this impression from looking at hi-lock-set-pattern:
(if (and font-lock-mode (font-lock-specified-p major-mode))
This condition seems to be different from what is documented.
Thank you and all the best,
Markus
