You also have ambiguity problem in the other model e.g. when you have
segments in your relation which are not defining a straight line... The
applications using such relations would simply ignore the ones with
ambiguities (e.g. not rendered). That would indicate the mappers what to
fix.

Detaching intersection nodes is not something usual. At the moment, the
complexity is more on managing ways with an increasing amount of relations
and an increasing amount of segments within the relations for a single
street.
