I don't know if this really counters my point, mainly because the tweet this is in reply to was deleted, so there might be more useful context there.

I don't have the link handy since I'm on mobile, but they've stated in a GitHub issue that they're not going to maintain v2 support, just activate the extended enterprise support to give users more runway. This just seems to be a mock-up of a toggle for that extended enterprise support and links to the extensions since they won't be downloadable from the consumer Chrome extension store.

I will admit that they haven't been clear (perhaps intentionally), but I have yet to see an announcement that explicitly states that they will independently maintain v2 support.
