I think there's a misunderstanding here, I'll try again:
What I proposed is putting the service definitions into /usr, never copy
or link them to /etc, never modify them (except by package updates), and
let s6 execute them directly from there.

If the local admin wants something other than the service as you ship
it, they create a completely new, independent local service and disable
the one shipped by you.

Thus you can update the definitions in /usr as you see fit, and the
admin can override things as they see fit. No machinery needed inside
the actual run scripts.
