At a minimum, it would be useful for others here to note that 3GPP is not the only party who has requested either a “block” of ports or an ongoing stream of requests. In all previous cases, the experts team has recommended - as here - that the applicant figure out how to run their services on one port. Although any individual request may appear to be inconsequential give the current rate of assignments, if we set a precedent here, we have to afford others the same opportunity.
