(If you are a representative of an upstream for which there exists an image and you would like to get involved, please see the Maintainership section below!)

It's not impossible, but it's not likely I would accept someone I haven't worked with IRL or know on a personal level. That's because I want some form of creative control over the direction and I want to maintain the existing code style. If I know you I'm more likely to know that this will keep working the way I want it to.

Show me good PRs, bug triaging, documentation fixes, whatever and you're a candidate if you ask for it.
