Could you expand on this response, please?

My understanding is that requests generate from XHR will have Origin
applied. This can be used to reject requests from 3rd party websites
within browsers. Therefore, intranets have the potential to restrict
access from internal user browsing habits.

Yes, but if no user private data is being exposed then there is cost
being paid for no benefit.
