Route concurrencies (multiple routes sharing a single physical road or
path) is most cleanly represented in the data model by multiple route
relations, each of which claim the road or path as a member.  This is how
OpenMapTiles currently deals with concurrent routes for roads, which will
be implemented in their next release.  The more we can get in the habit of
creating route relations, the easier it will be for route-aware
applications and data consumers to work with route data.

A "route" is a single feature and deserves a single object (consistent with
the one feature, one object concept).  Attempting to pack concurrent route
information into individual member ways is simply distributing the route
feature across many objects.  This makes work for data consumers and
mappers alike and in my opinion is more complex than having a single route
relation carry this information.
