Thank you for the quick response and modification of some of the link roads to base class. I did not know living streets do not exist in Armenia, thank you for sharing that information.

In your example (https://www.openstreetmap.org/way/203936144/history), there are apartment buildings concentrated in that specific part of Nor Norq and some of them are likely not intended for general public traffic. That would explain the community preference of service here. However, https://www.openstreetmap.org/way/207894129 and surrounding roads in the neighborhood are used to access housing and therefore would be better suited to residential. There are examples or service ways in other changesets, such as https://www.openstreetmap.org/way/540433576 and https://www.openstreetmap.org/way/984414071, which are likely accessible to the public (https://yandex.com/maps/10262/yerevan/?l=stv%2Csta&ll=44.523250%2C40.155119&panorama%5Bdirection%5D=338.099208%2C-4.421084&panorama%5Bfull%5D=true&panorama%5Bpoint%5D=44.523224%2C40.155042&panorama%5Bspan%5D=53.235945%2C33.264883&z=19.75) and look similar to nearby residential highways.

Thank you for making the changes from tertiary_link to tertiary. I did notice that there were some parts of Yerevan (https://www.openstreetmap.org/way/1302423824, https://www.openstreetmap.org/way/133000335, https://www.openstreetmap.org/way/1267353434, https://www.openstreetmap.org/way/49735127, and https://www.openstreetmap.org/way/303598193) that still retain link classification as opposed to base classification. I can help adjust these classifications if needed.

I greatly appreciate your time and such collaboration helps foster a more accurate map in OSM, and please let me know if I can assist in making any classification updates.
