Out of curiosity, who consumes these?

They're consumed by dotnet-optimization to generate the next set of PGO data to feed back into dotnet/runtime.

@ViktorHofer @jkoritzinsky Is your thinking that default artifact visibility is something that the VMR will be responsible for passing, rather than runtime setting this under certain conditions?

I think the default visibility should be a property of the VMR for PGO as we need to tell every repo (not just runtime) that its assets are Vertical-only.

For other scenarios (like filtering out RID-agnostic packages if we wanted to get rid of the concept of a main vertical entirely) I could see runtime controlling the default rules itself.
