What you're basically saying is you want developers to volunteer to give up their ability to advance their own careers writing features, and only fix security bugs in old junk that isn't entirely broken instead. You'd have better luck getting them to volunteer to be maids. If you want long-term community-driven support, then you'll stand a better chance getting it from developers focusing on making new things that are backwards compatible, rather than asking maintainers to keep old stuff alive forever. For example, Cosmopolitan Libc uses modern GCC11 to build binaries that support running on every distro all the way back to RHEL5, and I think that's the thing you actually want, except it's something you'll never see happen from distros, because they operate by a different set of incentives.
