Thanks! Maybe in the rationale section, we could also include some examples showing common alternative tagging methods to highway=residential + width=*:
highway=residential + motorcar=no: In Bangkok, there are 286 instances. Ho Chi Minh City: over 600. Jakarta: 2,867.highway=footway|path + motorcycle=yes: In Bangkok, there are 946 examples, 357 in Jakarta, and none in Ho Chi Minh City.service=alley: Bangkok has 1,629 instances, Ho Chi Minh City has a massive 21,329, and Jakarta has 1,350.
Just a heads-up: most of the service=alley usage in Asia isn’t for utility access as intended, but for narrow roads that provide access to the front of buildings, including residences.
