[openstreetmap/openstreetmap-website] a complete logical highway by name (#866)

I think it depends very much on your use case and your definition of what a "logical highway" is. It is not set in stone that a "logical highway" must stop at a boundary and that the fusion of two nearby streets carrying the same name is therefore "arbitrary". (There could be use cases where two parts of a street may be "the same street" in a postal sense but looking at it with the eye of who maintains the street, a change from highway=primary to highway=secondary might indicate the street becomes "different", and any fusion of two connecting streets just because they have the same name is "arbitrary").

I usually load all streets for the country of interest into a PostGIS database together with all boundaries, and then have them joined (or split up by geometry) for the particular use case. I think it is a too multi-faceted problem to expect to solve with an Overpass query.

Also, I think that it shouldn't be the job of the OSM web site (this is the issue tracker for the OSM web site after all) to offer interpretations on the data. Frankly I wonder why Overpass is involved in this discussion at all - the original poster had the problem that only a little part of a street was shown when he searched for it (basically, the first hit found by Nominatim). Could this not be solved by using Nominatim's dedupe=0 parameter and then displaying all search results instead of just the first?
