In order to completely disable automatic filling I'd add a function
which simply returns t to this list? That sounds like a nasty hack to
me. Also this only handles the case of auto-fill-mode…
By the way, I did not talk about filling HTML, but I guess it just
wasn't your “bloody business” to read my mail carefully, was it?

I'm talking overriding customization *in the special case*, that a
customization for a *parent mode* (which the user most likely did
without caring for, or even knowing of, a specific derived mode) is
*not reasonably applicable* in a derived mode, for the sake of
convenience for the users of the derived mode.
But please ignore this objection of mine, I rather thank you
wholeheartedly for ignoring this specific special case and instead
giving me the perfect excuse of an Emacs authority stating that it's
not my “bloody business” to care for my user's needs. In case any
user of my mode foolishly fails to understand this special notion of
Emacs development, may I forward her to your mail address, for special
guidance on the latest and greatest Emacs development practices?
