This is only about `read-file-name' - and MUST-MATCH being allowed to be
a function is quite new (June 2022).  If we have good reasons to change
the behavior because we find that the case when both MUST-MATCH and
PREDICATE are specified does not work intuitively I think it would still
be possible to tune it a bit.

But we have to know which behavior is more expected than what we
currently have.

Michael.
