There is a critical difference between these two situations. In the case of an arp sponge, the ixp operator has control of both the polling and the workaround. In the case of mtu management they would only have control of the polling, not the remediation. The point I was making is that an ixp operator can only control their own infrastructure. Once it's someone else's infrastructure, all you can do is make polite suggestions.
