Not quite a "commitment" but maybe a call to action? Or request for action? Or just any indication that there is IMMENSE community value in paying it forward to even a small degree?

should already know this / be bothered by it slightly or else they simply aren't.

I wholeheartedly, but respectfully, disagree John. While there is a large community of people who will do "this" (contribute) by default, the segment of people who don't contribute shouldn't be ignored under the assumption that they're just that way. I know I don't contribute to a lot of projects I use, or bug request on, because -I- don't see the value in certain tasks - whereas the project itself might find some value. I work with a ton of devs, in multiple industries and seniorities who feel similarly... As in, "if I can't contribute production code, there's no point", but that's flawed logic and I openly acknowledge it. To point out an example we've done here in Slack - we occasionally ask/remind the community to star Pants on Github. It's a call to action with minimal burden, but it's not the default behaviour for everyone 🤷

Heck, if you're coming from something like Bazel you've probably been pretty well conditioned to have low expectations re acceptance of PRs if you don't work at the sponsor company. We have opportunity to benefit from contradicting unspoken expectations ported in from elsewhere that are inapplicable here.
