I largely agree.  I wouldn't mind country-specific values similar to the
advantage that the UK has on this as previously stated, then let the wiki
work out what counts as largely equivalent in character for the renderers
to work with.  I feel like that would help a lot on the front and back end
of it.

If mapping tools map "dunno" to highway=road and <something_else> to

Agreed, highway=road is great for "there's something here, but I don't know
what it is".  Amazon Logistics mappers would be wise to use this value more
than trying to make a low quality or incorrect guess (and I hope they're
reading this because they're really doing a number on driveways and parking
lots in Oklahoma right now at a pace I can't keep up with, particularly
with OSMCha having broken RSS feeds).
