Don't the examples in the manual provide some guidance about how to use
the feature? I meant to make it clear that you can ask the server for a

Currently we don't have the capacity to keep substitutes spanning
multiple release tags.

I don't have the knowledge to evaluate the possibility of ranking
commits by substitute coverage.
