No, the Swiss basic network is not simply a collection of isolated ways
that are randomly interconnected. It is explicitly designed and signposted
in the form of routes between two destinations, which are split into
smaller segments between named guideposts. Guideposts do not show arbitrary
nearby locations, but the next and final destinations of each route. While
this is not always implemented perfectly because the network is huge and
might have grown organically in places, the routes are updated over time to
better follow these guidelines.

These routes can also contain permanently signposted deviations to avoid
difficult sections (even if the marked SAC level is the same), sections
that are closed depending on season or impassable depending on weather
conditions. This can't be mapped with a single tag on the ways. Maintenance
is also much easier with relations grouping the relevant ways and metadata
like start and destination.

Best,
Enno
