No. If you remove information which is redundant and when such removal will not result in even a single bit of sub-optimal routing what you wrote above is false "ironclad rule". Also the critical piece is that the determination when and what should be removed must be 100% automated. There is no way where manual intervention would be required for any scheme to work right. And your proposal does require manual NOC intervention as you have already confirmed today. The proposal from Pedro however is automated, adjust itself to topology changes as well as removed only redundant information where such removal does not impact a single bit routing optimality.
