What I'd like to see is some sort of tag on OSM objects (stops, routes,
etc.) listing the GTFS ID numbers so that tools can more easily connect
the two; that should be easy enough if someone defines a scheme and gets
the few relevant tools to use it.
The lat/long for stops in GTFS data is often questionable, so it would
be good to have some way for folks to be able to fix the stop locations
in OSM and not get overwritten by another import later. In many places
(especially in the US), GTFS data will change every few months, so if we
want it in OSM at all, we need a scheme that can deal with regular bulk
imports without losing quality where local OSM editors have improved
things by hand.
