IIRC there's some dependency between partial-completion and initials, so
doing it right may require more work.

There is no such canonical way to do it, and it's one of the facilities
that we need to add, indeed.  The read-buffer case is once such glaring
example (where we should change the default to (basic substring),
actually).
If someone has an idea for what such a canonical way should look like
(and no, using `advice' is not the answer: it's only "the canonical way
to do it for lack of anything better"), I'm all ears.
