In other words, you suggest that maxspeed should hold the speed limit that
applies, rather than 'what is on the ground'.
If such an approach is followed, could I suggest tagging 'maxspeed_sign=...'
as well as or instead of a source tag? For example
maxspeed=30mph
maxspeed_sign=no
maxspeed=30mph
maxspeed_sign=30mph
Then both the 'tag what's on the ground' and 'tag what's most useful' camps
could
have a way to record the information they want. For more complex cases, such as
the presence or absence of street lights, a source:maxspeed tag might still
be needed.
