I get the impression from reading your code, even though I’m a beginner,
that you want to burn through the steps.

With the “little” knowledge gleaned from the manual, it would seem to me
that things are reversed in your design.
• Major modes are designed to be customizable using hooks and minor
modes.
• Minor modes are generally independent of a major mode.

Comments seems to be handled in a major mode using “Font Lock mode”.

I couldn’t explain why but it seems strange: I don’t really see the
point of forming a function just to group functions.

It seems that you are defining a minor mode when you should be defining
a major mode (or derived mode).
