I don't think it's reasonable to have a list of distributions and to dismiss the rest of the world. The target should be "any reasonable mostly-POSIX system that is not very out of date", which notably includes systems that are not GNU/Linux. That doesn't really change the discussion much, as there is still "what is too old". I agree with your implied point that LTS systems especially those that tend to be super long term with support contracts are not a reasonable expectation for Free Software. Today, I'd say gcc10 is the oldest compiler that's reasonable for a system to have, and that projects should not require newer without a good reason.
