Managed App confusion

[cveld]

With regards to the Managed App readme.md we have a question with regards to the following paragraph:

Enable tracking resources for your template
Follow instructions at https://aka.ms/aboutinfluencedrevenuetracking to register unique GUID and update mainTemplate.json to enable tracking resources. This is a required step to avoid application package validation error during publishing and it is required for applications in the service catalog (internal organization consumption) and to the Azure marketplace (external consumption).

Following up on the instructions to register a newly generated GUID correctly it appears one needs to have a full fledged cloud partner portal (CPP) registration. Is this really required for publishing into a service catalog that lives in an Office365 demo tenant?

The documentation on
https://docs.microsoft.com/en-us/azure/managed-applications/publish-service-catalog-app does not mention this requirement.
