Hello again
Your statement is correct. And I have already asked in Iran's osm group how to register an alley in Iran:
Answer: It is better to register the alleys by users who have seen it closely, of course, for narrow alleys, we can add the width of the alley and whether it is car-friendly or not, and the use of the service=alley tag is very rare in Iran.
Thank you for your attention and happy new year.
