I have been watching the EE project for several years. Long spans of silence have happened before. Personally I tried, but could not continue using EE after the v4 transition and have moved to WordOps which has a vibrant community and is getting work done. I wish the EE team all the best and hope they come up with something good enough to bring me back.
I have been spending my dev time on WordOps backups, but still have the range from EE3-4 & WordOps. You can still get my tools here: https://github.com/microram/ee4-tools
