The wiki statement "Roads used for access to permanent human settlements or facilities should generally not use this tag" is on one level utter rubbish (because, as here, there's very often a mix of access to both fields _and_ the people who live in or near them) and also understandable as a pushback against (I think) a previous version of the iD editor's suggestion that "highway=track" be used for more than just agricultural access: https://wiki.openstreetmap.org/wiki/ID/Controversial_Decisions#Calling_a_highway=track_an_%22unmaintained_track_road%22 .
Whenever changing highway tags ideally you should do an actual survey, but if you can't do that you absolutely should look at the available sources, and here OS OpenData suggests that your "residential" road is probably functionally someone's driveway, as well as being the start of the track going west.
