https://docs.joinmastodon.org/client/collections/ doesn't discuss notifications

[nikclayton]

The "Implementing Collections" documentation is silent about the notification changes caused by collections.

Oh, that might be because the new notifications about collections aren't documented (e.g,. there's no discussion of the new notifications types for collections at https://docs.joinmastodon.org/entities/Notification/#type).
