1. Plates „on the ground“ can have abbreviations (English St./Str., Russian/Serbian ул., Serbian/Polish ul., Turkish sk. or cd. and so on) but their using contradicts to OSM recommendations not to abbreviate. Moreover, address plates and road signs can contain errors — I saw them IRL.

2. Map renderer/navigator can abbreviate — it’s not a task for mappers.

3. It seems, that it’s hard to match your local traditions with common OSM recommendations due your legacy. Well, the discussion ended. I see no sense to continue it. Have a nice day.
