There were in the past concerns about keyserver pollution, I believe. PPAs are now often pretty ephemeral, and frequently created and deleted, but all the keys will stay around forever, filling up name-based key search results. It would also reveal the name of private PPAs.
I don't think we should change the behaviour until we stop using the main keyserver network for PPA keys.
