This part is clearly a shared ownership service way, see OS OpenMap Local and Cadastral layers in JOSM. It may have been allocated a USRN, but it is an OSM service way.

I've carefully reviewed the changeset changes at https://overpass-api.de/achavi/?changeset=130213404
and can find no occurrence of the removal of USRN data from any residential road. A section of road has been made service where Cadastral data indicates it should be, and the USRN was removed in line with every other road in the area. Turning T ends have been made residential where they should be. You will need to decide if these ends should have USRN data or not; they are far from consistent in this area. Data in OSM should be verifiable.
The difference between residential, (unqualified) service and driveway is not as arbitrary as you suggest. The combination of Cadastral, OS OpenMap Local and imagery generally defines what is a 'public' road (residential or unclassified where appropriate), what is shared ownership access way (service) and what is the access to a single property or business for service=driveway. Please do not divide ways (eg left v right end of symmetrical turning T or make ways service due to the apparent absence of USRN in your dataset.
I stand by my edit.
