I would be careful here - 'dirt' is essentially a very vague term which
probably originates from the concept of 'dirt roads' here. 'Soil' in
the other hand is fairly precise, see
Only parts of the earth surface are actually covered by soil so if a way
is correctly tagged with surface=soil (and i don't know if that is the
case for the 400 cases you mention) this is something specific and
potentially useful and should not be degraded by turning it into
something as vague as surface=dirt.
In general i think surface=ground is the most sensible tag for tagging
ways that are just established somewhere without notible construction
work when you can't be more specific - it implies that the way surface
is essentially the ground there in its natural state. surface=dirt
OTOH can mean anything from the remaining tracks of a car driving
across a wayless area to a solidly built gravel road.
