This is not a good idea since sometimes, lines sharing a node aren't
necessarily connected

That's the point and really difficulct to make it work without a relation.
Debate is open about route=power which may be replaced by a more meaningful
tag (power=circuit for instance)

It's first of all a kind of challenge to produce a whole dataset.

End use cases are the same as public transport : automatize this kind of
chart production, feed simulators, routing software...

"Build it and they will come" is a bit necessarily since taking data from
GIS isn't a so common thing currently. BI and asset management are still
often separated from GIS
This has to change and osm can bring useful tools for that.

All the best
