[Tagging] Feature Proposal - RFC - (Hierarchies route=bicycle)

Hello, I propose a concept for contributing cycling route.
my english is bad, sorry ...
Bike routes are represented on OpenStreetMap as relations. There are many
official routes that are already present in the base, and more will come.
They can represent different types of itineraries: local, regional, national
and even international.
That said, international routes are often based partly on national routes,
which in turn are based on regional / local routes. Sometimes the regional
ones are based on the locals. Clearly, with the system of flat relations, at
least up to 4 itineraries can share the same physical path. In case of
modification of this path (for example, a new 2-km cycleway along the road
formerly used by the route), all the 4 relations have to be updated!
The concept of hierarchical relations makes it possible to avoid this
edition nightmare, so that one single relation has to be modified, and this
modification is automatically applied on the other 3 routes.
