Import: Bus stops from GTFS

The GTFS wiki page is definitive about preferring the latter, see Interpretation of deprecated gtfs:feed=* and other “Interpretation of deprecated” subsections on the page. It seems this info was added in March 2024 with the comment “Incorporate approved proposal GTFS tagging standard” so I think it’s up to date.

For the proposal I mostly wanted to get a consistent standard through.
The main benefit of gtfs:stop_id:IL-MOT is that if script/feed adds information to the same object it is clear which feed it came from.

The deprecation of gtfs:feed got the most pushback on the vote, which narrowly passed. Since we now have a good standard, making small changes is easier.
One of them is [RFC] Feature Proposal - GTFS Tagging standard - #40 by spaanse .

I want to suggest if you are going to use the gtfs:feed approach, please fallback to gtfs:stop_id:IL-MOT if tags for other GTFS feeds are already present. (or downgrade the other tags to that scheme and have yours be the authorative one)
