Is it OSM recommendation? Would you please provide a link to it?

If not — I think this way has very limited profit. If everybody support it, Riga will be filled with hundreds disused shops.

OSM not an archive.

If anybody want to look into history of a territory — can dig into osm database history.

Thank you!

bus 5084 not found there https://www.1188.lv/satiksme/pilsetas/cesis, not on CATA website. What's bus route source?

Yes, other routes too.
Hope I fix it now.

The fix was
- remove old wrong platform
- move new platform to the correct position in stop platform llist
- assign role in route (platform)

I recommend to use JOSM editor for works with routes.
There are plugin idel for stop platform replacement: https://github.com/praszuk/josm-movemembership-plugin/
One click — and platform replaced in all routes :)
