Think about there is only -A-D-B- , where A and B are a node in such a
relation. Everything is fine.
Now someone adds a way A-C-B. This mapper have to do several things now:
Check, if he make a way of a relation more directer as it was before.
Problem1: Find all affected relation.
Problem2: If he adds a footway, he can skip bus-relations, but what to
do if access is unclear?
Problem3: Editing the route will end in a try'n'error: Does josm
"routes" correct if I add this node?
Problem4: No mapper will know about to do these checks, because it was
never ever a problem adding a simple way or changing highway=* or access
Same if a mapper changes the access of any way. Maybe its easy in
Cities, if necessary nodes are pretty close. But in rural areas it could
happen that you edit/add a way somewhere and you destroy a relation
which has one node 1km left of your mappnig area and the next one 5km in
the right. This isn't really practicable.
