I can live with adding the place=city tag if that will settle the matter. I still argue that this leaves some confusion (admin_level=4 implies that Ashgabat is a province even though it is not) and would be happier if the admin_level=4 relation were deleted, but suspect that would eventually lead to someone else adding it back anyway. So please add place=city and let's leave it at that.

Koreller, "equivalent to" does not mean "the same as". Ashgabat is a city, not a province.

I refer you to osm.wiki/Turkmenistan_Geoname_Changes, osm.wiki/Districts_in_Turkmenistan, and osm.wiki/Turkmenistan#Administrative_Subdivisions. These articles are based on information I collected during my tour of duty as a diplomat in Turkmenistan.

Ashgabat has had its own administrative boundary and has been separate from Ahal welaýat since 1992. The capital of Ahal prior to Arkadag was Änew. But that is irrelevant. The relevant fact is that Ashgabat is "equivalent to" a province (i.e., has legal status equal to the legal status of a province) but is not a province and thus should not have a boundary line tagged "admin_level=4". I can say that ibuprofen is equivalent to acetaminophen in terms of pain reduction, but that does not make ibuprofen into acetaminophen. By the same token, saying Ashgabat has legal status equivalent to that of a province does not make Ashgabat a province. Please correct this error.

Ashgabat is not a province. It has the legal rights of a province, but by law is categorized as a city. This relation at admin_level=4 is incorrect and should be deleted. Turkmenistan has five provinces and Ashgabat is not one of them.

Perhaps the wiki needs to be corrected, since a border is a specific type of boundary, and both are by definition and in reality lines, not areas.

Well, that's interesting when you consider that according to the Cambridge Dictionary, a boundary is "a line that divides two areas or forms an edge around an area:
The mountains mark the boundary between the two countries." https://dictionary.cambridge.org/us/dictionary/learner-english/boundary

David, greetings,
Boundaries by definition are lines and not areas. I ask that you not remove the tags.
cheers,

What is the point of adding labeled junctions like this?

Please stop removing addr:city and addr:district tags from villages in Turkmenistan. The reason they are needed is to differentiate among villages with the same names across multiple districts (etrap) and rural councils (geňeş). Please see the wiki article osm.wiki/Turkmenistan#Note_on_Villages

That is incorrect. The country itself is admin_level=2. As a city, Ashgabat should be admin_level=8. See osm.wiki/Tag:boundary%3Dadministrative#Country_specific_values_%E2%80%8B%E2%80%8Bof_the_key_admin_level=*

Karizek etraby is part of the city of Arkadag. Please also see osm.wiki/Tag:boundary%3Dadministrative#Country_specific_values_%E2%80%8B%E2%80%8Bof_the_key_admin_level=* for use of the admin_level tag in Turkmenistan.
