I have a pod doing it too, just figured I'd bring it up, not actually something I would actually argue about. But the splitting by medium just makes it easier for clients to just be good at one thing OR not have to filter themselves when querying. Like I'm imagining Podverse, would essentially end up making a query for this list on each tab, but it was "this list is my podcasts I'm subbed to", this is the episodes I favorited" "this is my list of episodes for onboarding people to nostr", etc then that client doesn't have to do filtering and they are less of a burden on the relay. Might be worth some testing.
