@SimenB, looks reasonable. We could move up notPermittedMethod helper to the jest-resolve root and wrap it with once, so we get just one warning until jest-resolve reload.

@SimenB should it be a best practice recommended for everyone?

Summary
As mentioned here: #9841 (comment)
This makes me think that we might want to rethink the warning... Is it safe to include this change?
@antongolub @thymikee @jeysal would love your thoughts
EDIT: One thing we can do is only warn once per
jest-runtime(meaning per test file). Better than potentially flooding the output at leastTest plan
Green CI without flooded output
