Indeed, I don't understand the difference between guideline and rule.

I also don't understand why phrases like "probably ok" are useful in
this context.  To me that sounds like: "it's ok for amateurs, who have
little knowledge about Emacs conventions, to do it, because the harm
will be quite limited, but real pros wouldn't do it because they are
aware of some obscure problem that might arise even if only with low
probability."

I'm only asking for a clarification of the guidelines, so that the next
time when some of those amateurs tells me that it's "probably ok" to
enable things automatically, I can point to the manual an tell him that
it violates the usual guidelines.
