I'm not sure this feature is a good idea. We may want to be able to disable the MasterMinter contract (in case of an emergency). We have several options:

  1. Change the USDC masterMinter to point to a different contract
  2. Set the MasterMinter minterManager to some random address - of which 0 is the cleanest.

We should discuss this with the team.

Summary:

  1. We need to discuss whether to allow minterManager to equal 0
  2. Use expectError instead of expectRevert to check error messages
  3. If we decide to require(minterManager != 0) we will need to delete all unit tests that check what happens what it is 0.
