Regarding point #3. I am on the Hive Engine/Steem Engine team. I am not an official spokesperson, but I can tell you that Steem Engine is not going anywhere. While it is true that we are now supporting the Hive blockchain, Steem Engine created tokens and platform will remain active. You probably won't see any more innovation for Steem Engine, but the ability to operate NFT's and custom tokens on Steem Engine absolutely remains an option and some tokens still have not migrated.
