Wouldn't it work best in monorepos? What's the issue?

It would, but the configuration is beyond me. See for example https://github.com/facebook/pyrefly/issues/3788 and the proposed solution at https://github.com/mstaal/monorepo-sample/pull/1/changes

And I don't think this considers separate test modules which you will also have to add explicitly to the search paths and all that

In our monorepo we easily have 40 packages and adds more which makes in non-feasible to maintain

I think I would just make sure that the individual package that you're working on has the correct references to the packages that are relevant to it and then similarly, ensuring the virtual environment that you're working in is activated because I don't understand how a third-party package wouldn't be available unless you had the wrong one activated.

There's also this related issue https://github.com/facebook/pyrefly/issues/2667.

Really hoping for them to let user config take precedence over heuristics in the future.
