Not necessarily. E.g. they can share the same (buffer-local) variable,
like `overwrite-mode-binary` and `overwrite-mode-textual`.

Yeah, you can't name the minor mode `ConTeXt-en-mode` because that needs
to be a function which enables `ConTeXt-mode` as well as the "en" minor mode.
Tho maybe you can have a hack whereby the `ConTeXt-en-mode` minor mode
calls `ConTeXt-mode` if the buffer is not yet using that mode
[ And there's that "maybe" again. ]

That is indeed part of the motivation behind `major-mode-remap-alist`,
tho I haven't yet tried to push that use to Emacs's `master`.
