I would assume, as an open protocol, ActivityPub can adapt and change over time, so that newer services can be created with newer features. Existing services will also adapt. Or we get say Mastodon2.0 which is backward compatible with 1.0. Not sure how the data base works that stores data, but I would guess it is seperate from AP so data can be moved just like data can be downloaded and uploaded to a different instance. So at some point we can download from a AP1.0 instance and upload to a AP2.0 instance.
