[Tagging] "Relations are not categories" excepted for "type=network" ?

For me the difference between bus routes (or walking routes, or cycling
routes or ..... routes) and a collection of McD locations, represented in
OSM by POIs (or buildings), is that you can traverse a specific route only
by using the roads and paths along that route but you can navigate any way
you want (within reason) to get to a specific location. For me they are
evidently different in nature.
We are not talking about collecting all bus stops in a city independent of
the routing (that would be a simple collection).
It is helpful to be able to put the routes on a map. And since they are
fixed and cannot be calculated at run time by a navigator, I do not see how
else we can map routes conveniently in OSM.
I already mentioned the reason we do not want to put ALL the roads/paths for
a cyclenode network in a single relation: cyclenode networks are large (some
are very big indeed). It becomes difficult to manage these with tools we
have available. So we just map the routes between cyclenodes (or for busses
between the two end points of a route).
Putting the marked routes in route relations and putting those relations in
a network relation simply reflects reality (they all belong in the same
cyclenode network).
The same is true for individual parts of a long-distance walking route.
Those long-distance routes which have all the ways in a single relation are
painful to manage with our current tools (I am thinking of mappers rather
than consumers).
A site like Lonvia hiking works very well with the current solution with
relations and "super-relations". If it ain't bust, don't fix it. Please.

If you don't understand that a collection of "all bus routes from
operator XYZ in my city" is not different than a collection of "all
McDonald's restaurants in my town", then I cannot argue any more. And
if we tolerate the first, we cannot refuse the second.
