What to do if you already signed the CLA

Individual signers

Corporate signers

• Your company has a Point of Contact who decides which employees are authorized to participate. Ask your POC to be added to the group of authorized contributors. If you don't know who your Point of Contact is, direct the Google project maintainer to go/cla#troubleshoot (Public version).
• The email used to register you as an authorized contributor must be the email used for the Git commit. Check your existing CLA data and verify that your email is set on your git commits.

@starsaminf Can you provide some motivation on these changes? Neither of these requirements look like they should need to be explicitly listed

I can confirm that grpcio will be pulled in via google-api-core (a dependency of all the GAPIC libraries). Similarly a minimum version of setuptools is required by google-auth.

Alright since we've determined these are brought in somewhere else, I'm going to go ahead and close this.
