Subscription properties: what's actually new?

I picked this one on air. My first read was that it would show who is subscribed or unsubscribed to specific channels, not just "unsubscribed from all."

Zach Hussion pushed back with "Didn't they have that, though, before?" and I get why. Where I landed: "you had to know the exact subscription name sometimes to find it versus this looks like a checkbox."

Chris Carolan came at it from another side: there's "a lot of friction on purpose" here. Whether this is new or just easier to find was the real debate.
