Transit Gateway was announced at re:invent 2018. That's a few months ago. DirectConnect Gateway and Transit VPC were announced the year before. I would guess about nobody is currently in production with Transit Gateway.

Except you can’t yet do cross-account transit, which makes their Transit VPC offering pretty much useless. The whole point of transit is so you can talk to other VPCs across accounts.

You can. Share it with Resource Access Manager, can even share it to accounts outside of your own AWS organisation.

You can connect transit gateway to VPCs owned by different accounts.

Will BYOIP be sharable with RAM?

Currently testing it, can do lots of fun stuff with the routing domains. Will roll it out once they get Direct Connect support in Q1.
