I missed the fact that there's already some discussion of working with remote builds in the command guide. I don't think it needs to be changed.

Separately, @phosek pointed out that there might be an issue with changing the way paths work in coverage mappings based on -fdebug-prefix-map or -fdebug-compilation-dir alone. Mind holding off on landing this until we pick some way to resolve the issue?
