I'm not sure it's a good idea to remove them from completions.

Which part is silly?  The above text simply describes things as they
stand, without forcing any particular choice.

Which it is.  We simply added the note about minor modes (which is
actually not specific to minor modes, it also holds for many plain
variables), because it has been found to be a common misuse.

That's fine.  A very common situation is a file that you're the sole
author, so you put any random personal setting in there without having
to worry about asking Will.  And then you publish it on the web (e.g. it
could be an Elisp package), so anybody who opens it in Emacs gets your
preferences imposed on himself while viewing your file.

17 minutes and counting... how's that for impressive?!
