I see the logic.

I still find returning a list of mimetypes useful though - if user wants
to implement an additional filter on top of a-s-f provided by major
mode, having a list of mimetypes as input is more flexible.

But we need to document that the final choice will be taken as the first
element from what a-s-f (possibly adviced) returns.
