the compatibility matrix is exactly what I'm wondering about too. It's far easier to test against a single version of a dependency and deploy against it too.

the compatibility matrix is exactly what I'm wondering about too. It's far easier to test against a single version of a dependency and deploy against it too. I can't help but wonder if there's a better way that could scale to open source. I personally like monorepo-based development a lot - where you have one version of every library for the whole repo, and a total ordering on changesets (and a strong test suite to catch regressions). But organizing open source into a monorepo or even a virtual-monorepo seems tricky. Might be the sort of practice that can work well for companies but not so much when decision power is more distributed.
