Allow integration user license for Nintex Salesforce integration

Many Salesforce orgs have integration licenses included with their Salesforce orgs, and it would be incredibly valuable to use an integration license rather than a full Salesforce license to connect Nintex. That would allow us to use a unique user for Nintex integration to track activity by Nintex, and it would prevent having to use a single full Salesforce license on this integration user. It is also very useful in cost savings and license allotments.
