and casually break API and reloading SDN during the upgrade, while
triggering such updates might be not the best idea to do in the first
place it would be at least good to call it out here.

FWIW, if we'd walk the full mile here we probably would keep the old
param as fallback and check the node version from the pmxcs in memory
kv store in pve-network to determine what param to send to the other
nodes.

That said, I can live with skip doing that, it is a major release
after all. Just ensure you have upgrades on your mind or, if you had,
add a note for that next time.
