Adding your own passes was possible before (I used websites to create passes on the phone; apps existed too) however that's been a hurdle. I wonder what the security implications of this would be. Could people snatch a QR code on my paper ticket to go to a Taylor Swift's concert instead of me?

That's a feature, not a bug. It means you can sell the ticket if you can't make it. Thankfully (/s) we have Ticketmaster with rolling codes now, so, no reselling.

This also means I can do it twice if I choose so.
I can't speak for all things, but I found that venues will often use like a rotating QR code or rely on NFC. I'm sure if this is something like a ticket for a concert, you'll just rely on the existing pass support from whatever service you're using because it'll require something more complex.
The way I'm interpreting this is that it's a way to abstract stagnant QR or barcode passes for smaller businesses and libraries. We'll see at the WWDC though.
How do they get your paper ticket?
By using their smart glasses or 20x zoom camera to take a picture of it when I take it out of the pocket at a grocery line?
Thieves could snatch my paper ticket from my hands before, but at least in that situation I would be aware of it.
