As I said, it is an issue as old as OSM that isn't likely to be resolved
here and now.  You may recall in the early days of segments, there was a
capability to add a path from tracing, which didn't appear on the map, and
then when it was surveyed, confirmed and named, it would have a rendered way
that was part of the map.

Personally, I think people shouldn't  map areas when they don't have any
knowledge of the topology and layout because I think fixing errors takes
several orders of magnitude longer than the tracing.   Any perceived time
saving is illusory, when someone has to visit the area sooner or later
anyway.  I think having a complete map is very long term goal, and having an
accurate map is a higher priority.  I'd much rather a street be missing than
wrong, and accuracy comes cheaper when accurate work is done the first
time.  OSM remains a successful project, and when we have people who are
mapping underground pipes and antennas on top of buildings, volunteer time
doesn't seem to be the first consideration.

However, I understand that the community has a divergence of views.  I
understand that everyone makes mistakes, even from the most detailed survey,
and accordingly I'm sure you will find as many supporters of your position
as detractors.

If everyone makes sure that the source tags are updated accurately, and
continue to discuss errors we find in a cooperative manner, hopefully we'll
all manage to map happily every after.
