[Tagging] Tagging Cycle Route Relations vs. Ways

The Cycle Routes Wiki Page
"It is preferred to tag the cycle routes using relations instead of tagging
the ways."

If I come across a route that has the Ways already tagged with the name
<https://wiki.openstreetmap.org/wiki/Key:name>=* of the route, can I delete
the name <https://wiki.openstreetmap.org/wiki/Key:name>=*s in the Ways and
just create a Route Relation with the name?

I assume this is not prefered because a number of applications use the
names in the Ways themselves and not the Route Relation, most notably

However, some benefits of doing this might be:

   - Takes up less space in the DB
   - More tags that apply to the whole coute could be added to the Relation
   like surface <https://wiki.openstreetmap.org/wiki/Key:surface>=* and
   source <https://wiki.openstreetmap.org/wiki/Key:source>=* (like the
   official map of the route).
   - Ways with two or more routes wouldn't be tagged name
   <https://wiki.openstreetmap.org/wiki/Key:name>=route 1 & route 2
   instead have their respective Relations. This could help with preferred
   routing/data usage in general.

I would propose that *all* routes and their names should be tagged in a
Relation and *never* the Ways, even if the Route Relation only has *one

This way data consumers know that all Routes are going to be relations.
Also future Routes mapped that share the Way of a Route that does not have
Relation, won't require the mapper to shift all of the data stored in the
Way to a new Relation.

Also, if Proposed features/Relation:street
<https://wiki.openstreetmap.org/wiki/Proposed_features/Relation:street> is
ever approved, this would help establish a consistent OSM-wide routing

*As for now*, I do not think that we should be deleting the name
<https://wiki.openstreetmap.org/wiki/Key:name>=*s of Ways. However, I think
osm-carto *should* render and *prefer* to render Relation names for Cycle
routes over the names of the Ways. The Editors should also somehow
influence users to map Relations for Cycle routes instead of naming them.
