If that’s what all good maintainers do, and intend to do, there’s really no reason for maintainers to tempt themselves by using awful “open” licenses that allow them the loophole of doing what they want with the software they create. Plus who wouldn’t want to codify that they’re not an asshole?
It shouldn’t be hard to get maintainers that intend for their software to “amount to something” to adopt it, and it would bring a sense of comfort to the people that rely on the software that you write when you announce that it’s the new default license for everything in your repos.
