Hey Will, Yes, the field mask helper is actually pretty simple. You can also pass None as one of the paramters, and it will compare the other object to a blank version of the same type. I just did some simple experimentation and it doesn't seem as though it handles oneof fields (like bidding strategy) very well. For example, if I compare a campaign with manual_cpc.enhanced_cpc_enabled = True to another campaign with manual_cpm set to {} it doesn't acknowledge the change in field, it just seems to think that manual_cpc has been unset.
In general the way to unset any field (in your case, to remove the resource name for a portfolio bidding strategy) is to leave the field blank and manually add the field to the update_mask. The API will see that you intend to update that field, see that it's blank, and assume you meant to return it to it's default value, in this case an empty string. At some point in the distant future I'd like for the update_mask logic to be more implicit and require no manual intervention, but that's unlikely to happen any time soon. If you have any more questions or issues related to this, please feel free to add another issue to the GitHub repo.
