Hello ChromeLotus!

- https://www.openstreetmap.org/way/135437282 - plays a role of a link, but, yes, not physically separated as a link; corrected to tertiary
- https://www.openstreetmap.org/way/23635109 - my not intentional blunder. It is definitely a tertiary road.
- https://www.openstreetmap.org/ - also, not physically separated, but has a lot of "through" traffic, so corrected to tertiary road (+ simplified the roads around because they are definitely "recorded" from GPS with too many dots without meaningful turns)

Regarding "highway features were updated to service from living_street and residential".
*) There are two links, but they are the same changeset. Did you have another changeset to highlight?
1) There are definitely no "living_street"s in Armenia, so changing from this type to "residential" or "service" is an improvement
2) I, once, casted most of the streets in those neighbourhoods from "service" to "residential" but (if I remember it correctly) that change was rolled back to "service" by some logic (in the talks with local mappers).

E.g. https://www.openstreetmap.org/way/203936144/history - I mapped it as residential in V9, but in V8 and V10 it was typed as "service".

I use the principle that "residential road" should lead to some other, residential or service or driveways (and, thus, usually, not a dead-end, but branches into service roads).

So, I, personally, agree with your suggestion to cast "service->residential" but do not know where/why this difference is important to "fight" others.

@Vasak87 - why do you prefer these neighbourhool roads to be service type rather than residential type?
