[Imports] Import of public transport platforms in Styria (Austria)

I've forwarded the question on the use of the IFOPT-number to the talk-transit mailing list (https://lists.openstreetmap.org/pipermail/talk-transit/2013-December/001663.html).
The operator is not included in the data provided for the import, and often there will be several bus line operators stopping at the same bus stop. However, the operator tag is included in the bus route relations, so it can be deducted from that, if someone wanted an "operator" (or operators) for the bus stop.
I think the is_in is necessary for the following reason: We only have boundaries down to the level of communities ("Gemeinden") in OSM, but the bus stops are often labelled with the name of villages, sub-parts of the communities, which sometimes don't even have exact boundaries.
Here are some examples, where I think it would be impossible to derive the "complete name" (town and name of stop) without the is_in-tag:
http://www.openstreetmap.org/node/1487738866: Although this stop is geographically still in the city of Graz, this stop is in Fölling for everything related to public transport (most important for tariffs, but also for a unique name ...).
http://www.openstreetmap.org/node/1801654560: This stop is closer to the node called "Fölling" in OSM than the above stop, however it is in "Prellerberg" (there is not even a place in OSM with that name).
http://www.openstreetmap.org/node/1735061993: This stop is named after the community it is in: Rettenegg, BUT:
http://www.openstreetmap.org/node/1735061989: This is the platform for the other direction, which of course has the same name, but is geographically already beyond the border in the next community (Sankt Jakob im Walde).
One could of course state, that the bus stops should be renamed, but since that is not within our scope, I still think, the is_in-tag is required for identificaiton of the bus stops.

We just looked at another bus stop import.
This issue of the IFOPT/GFS numbers has already came up, without any
good solution so far. These global routing ids are useful and I think
belong in OSM. We don't have a standard tag, making it very difficult
for somebody to actually use them. Rather than putting them into an
import specific namespace, instead could could you figure out a proper
tag for them, and put it here?
Whatever comes out of that conversation, use it for the import. We
don't have anything...
- You might want to look at the operator tag.
- I don't think we need the is_in, right? We have the town boundaries
in OSM. Its fine if the same name is used over and over again.

All others will have to checked and merged manually. This has already been successfully done with an import of all doctors in Styria.

However, most of this disused platforms will be in the capital city of Graz, where I and other users know, which stops are the ones disused, so they can be excluded during the manual import (all platforms in Graz should already be mapped, so this area can be excluded from an automated import). In the end, there will probably only be a handful of disused platforms in the end. On the long run, all bus routes should be mapped; then it will be easy to find unused platforms.

Should this be imported to OSM (as ref=* or something different?) in case we later receive open timetable or realtime data which needs to be connected to the stops? Or are there other ways to match timetable data to platforms? These IDs are not visible to anyone standing at the bus stop and I have not yet encountered them anywhere else than in that file - from what I've read so far this is a strong reason not to include them. However, I want to be sure we don't need them later.
