but without the actual will and motivation to keep supporting that software to pump out software and publish it.

TBH, most software will never be used my many so needs no support. Also, I think lack of long-term support is not the same kind of problem it used to be. Back in the day, when the original author dropped support it was a major investment to get someone else up to speed. Now fixes and enhancements can be done by LLMs as well, given a somehwat competent software developer.

But in general: The newer the project and the more bells and whistles it has, the less I personally would want to make it an essential piece of my workflow.
