Because any company reaching monorepo scale will have integration tests that cut across the boundaries of your projects. It's possible for an outside contribution to break your corner of the repo, but the flip side is that you will know much more quickly if your own changes break another part of the repo.

Heh. This makes a couple assumptions that I only can wish were true: (a) that people won't go to monorepo until they hit some huge scale, and (b) that people will at that point have good test coverage.
I completely disagree. My company is absolutely “monorepo scale”, but I also know we’re nowhere close to having the test coverage to allow people unfamiliar with a project to freely land changes in it.
