Agreed.

A related place where these could be used is on "superrelation segments" 
- for example 
https://www.openstreetmap.org/relation/4087754#map=17/54.29405/-1.22487 
, which is part of https://www.openstreetmap.org/relation/4087652 .  The 
"thing with geometry" has a name that includes from and to in the name, 
so that anything that processes that directly will get the name wrong: 
https://map.atownsend.org.uk/maps/map/map.html#zoom=18&lat=54.294414&lon=-1.226398 
.

Excellent!

The other bit of this (not really an issue for this list though) is 
display of that in OSM-based maps and apps - currently even some 
hiking-focused OSM-based apps fail to show what I'd have thought was 
basic information (such as "am I actually legally allowed to walk here") 
so enhanced relation support is likely a big ask for them.
