The only goal is enrichment.
The goal is a more diverse body of climbing media: independently-authored work, shaped by people who care about what they're documenting and who want to share it.
Stele can't make media diverse, so it focuses on tools that climbers can use to make the work easier.
Durability
The goal isn't short-term and Stele is mostly one climber on personal time.
So what if Stele stops? Each project is self-contained and dependency-free; any project can be picked up independently by a future developer who cares about that piece. Hosting is trivial to reproduce. Sites are hosted on NFSN, source at Codeberg.
Community benefits from Stele projects should outlast Stele itself.
