We talked it over, decided I would do the test suite.
I started, found the bad practices, and showed how I could turn it into a fully automated system, new versions could be tested against, and if it works, it could output binaries for every system.
The response was, 'No don't do that. I like doing it manually. Means I can check for breakage.'
Followed by my PRs and issues being closed, and my emails bouncing.
It's easy to point issues and not do anything to help.
