I want to make a new definition for the the service=subkey to better define highway=service when used to map the the odd public, maintained, paved, yet extremely narrow, meandering, and often parallel or inconvenient nature of a lot of rural roads in Asia that are used to access sections of farming lands, river embankments, and other roads that run parallel to major/minor roads to allow access to tracks, footpaths, occasional service buildings, and paths, similar to a Alley in an urban setting, which is also a variant of highway=service.
I look forward to more feedback before drawing up a wiki page, but you can see my reasoning and 2 good examples below. This is something not covered well by track+grade1 IMO and below unclassified IMO.
