I'm an avid rock climber and open source enthusiast. I want to build

Many climbing walls/crags/areas are currently defined as nodes in OSM. In
contrast, in my proof-of-concept app users can define and save crag
boundaries by drawing polygons on the map. The search function would then
use spatial queries to find features contained within a polygon.
The linked photo below illustrates typical layout of a climbing area. Crag
boundaries are often loosely defined by climbers... so I'm not sure whether
saving those polygons to OSM is a good idea.
Also I have looked into using Relations but the concept seems rigid for
this use case as it would require the users (or the code) to associate
climbing routes to a relation. Perhaps I misunderstand the concept of
I'm looking for guidance and suggestions on how to best implement this
feature. Having all geo-data in OSM (single source of truth) would be
ideal, but I can just store those polygons in my own database as well.
Here's my proposal:
