Let me explain with an example.
Have you ever seen the route of the Tour de France?
It is made of a series of stages.
Usually, the stages are connected, like the ways of an OSM route.
But sometimes they're not. There is a gap between two stages.
And nobody cares about why, what there's in between or how the cyclists
bridge the gap.
The specification I'm trying to suggest is exactly that.
There is a gap in an OSM route and the sole idea is to bridge it.
We must indicate "go from here to there in an unspecified way".
It is just to
* make sure that those who follow the route will go "there" and not
* indicate to validators that there is no mistake and that the route
is connected and maybe looped
That there are paths in between or not, what those possible parts are
called, that the route may exist and just be unknown, that there should
be paths but that there is a map bug, or any other reason for a gap, all
that is very good for a note=literature but is totally irrelevant for
the attempted specification.
They were mentioned because the idea evolved from a path feature to a
