Are there metrics for package download counts from the official cache?

I was wondering if there were metrics behind downloads from the official cache.

It’d be nice to get an idea how popular a package is.
We could see if popular packages need a bit more maintenance attention than they’re getting.
Or whether it’s safe to sunset an old package. etc

I’m sure there are loads of other cool insights that could be gathered and it doesn’t need to be aware of who is downloading what so it’s plenty private.
