It would be nice if we could remove this file in CI. That way we'd be notified if we by accident installed a module that didn't support any of the versions we test in CI

I don't think it's necessary for 2 reasons:

1. We already explicitly use --ignore-engines in CI, so this is basically just redundant and only also applies it when working locally.
2. We could have an explicit job that checks that. Short of that, we have integration tests that use a sandbox that install dd-trace like a user would (which does not include the file)
