Review comment:
I think it would be great to add a little context here. In which
situations you would like to do that? I am not 100% sure here if we are talking
about "user facing' mocking or "contributors" mocking. If this is user-facing,
then it would be great to explain when mocking might be useful. If this is
"contributors-facing" then it should be moved to CONTRIBUTORS.
