I implemented Booter McGooter because the upstream projects did not support this feature.
I do not have the time and energy to collaborate with the upstream maintainers to make this a first-class feature of Mirth Connect or the Docker images from NextGen.
Please collaborate with the https://github.com/nextgenhealthcare/connect or https://github.com/nextgenhealthcare/connect-docker projects to take the features from Booter McGooter and make them native features of Mirth Connect. Please reference this issue in any PRs you make to connect or connect-docker.
The goal is that if loading the server ID and env name is part of Connect, then Booter McGooter does not need to exist.
