i was thinking of a rule saying for instance 'the siblings of
dir/foo.pdf are dir/foo/*.org'.  that might be a bad example.

but even in the "normal" case, i'd like to be able to define
find-first-sibling, or maybe find-last-modified-sibling, or
show-sibling-other-window, or...  for that i'd use
find-sibling-file--search (i think).

in other words, i am thinking that there are two parts to this new api,
one is defining/listing the siblings of a given file and the other is
actually finding (in the find-file sense) one of them.  i was asking for
a public way of accessing the first half.
