Less likely, no. Easier to fix, yes. There is only one thing that can break: Docker. And Docker is developed by a company who's job it is to fix their software. With homebrew, we rely on each package maintainer to fix their software, and that fix to be pushed to homebrew.

What? I've never had to upgrade a kernel to use docker.
The only real dependency is OverlayFS, but that will stabilise eventually.
