i'm well aware that a pull-request with a fix is a lot of work. i don't pretend to have the capacity to do this, with all the rest i have to attend to.
it just doesn't sit well with me that, i am aware of something being broken, and not telling about it to someone who would otherwise want to know about it.
In my opinion maintainers can easily run a "hey robot, scan my code for risky patterns" to get a rough list, or they can solicit unreviewed contributions, but otherwise better not to add noise.
