It does seem logical. Especially as any street currently mapped with
an associatedStreet relation which is then split at a later date (by
someone adding a bus route, change in speed limit, or whatever
reason they split it) will end up as an associatedStreet relation
with two street members anyway in all likelihood. I doubt the
editors are at a stage where they can split such a relation into two
separate relations and get the right houses with the correct street
section automatically (and for some streets I can imagine this will
never be possible automatically reliably anyway). I'd be surprised
if there aren't already a number of associatedStreet relation with
more than one street member, but not sure how easy it would be to
find out.
