The good solution is rock-solid, backwards compatible APIs on all levels. That way the work to maintain software would be much lower, making it possible to focus on doing some rare bug-fixing only. In open source in particular this should be a no-brainier, instead of all projects ruining things for each other by ignoring backwards compatibility.
The rock-solid backwards-compatible API would include, for example, being invoked with the command "screen -x", and being installed with "apt install screen" - at which point it's the same screen project under different management, not a new project.
I was referring to the APIs required by screen itself to run. If screen is anything like any software I know anything about a fair amount of limited developer time has to be wasted on keeping up with random third-party stuff changing/breaking. Even if that is not the case, if we get more stable software in general that would mean maintainers of free software could take on more projects each, meaning there would be a higher probability that someone could be around to fix bugs in screen.
