I think you are more than welcome to make a Fork and do this. You can backport all fixes and not implement new features.

I think new features is one of the core reasons the projects gets more contributors, and it sorely needs those. I understand why the focus is now on that.

If you want stability, I’d suggest maybe finding some likely minded people and go and maintain a Long Term Stable version.
