Hear, hear!  Maybe not "mostly" - depends on the use case.
But certainly _in general_.

Yes, relevance (score) varies, depending on the use
case.  In general, what's relevant is scoring the thing
that is represented by its name, not the name itself.

And how is that relevance determined?  Typically, you
need to use the PREDICATE arg to `completing-read', to
match not only the name but also the accompanying data
in an alist entry - data that can be super rich.

Of course, that works only for an alist arg, not for
an obarray, hash table, etc.  But there are hacks for
those other arg types (property on a symbol or string
candidate, for example).
