In my experience dealing with cross-connect LOAs at Equinix SY1/2, SY3, SY4, SY5 and ME1, Equinix have always requested an LoA from the Z-side. Never heard of an LoA not being required for a cross-connect otherwise, how would they know it's a legit request? However, cross-connect LoAs are beyond the scope of this topic.
I've also only seen this with smaller customers requesting their upstreams allow the route through their filters. If upstreams don't ask, how do they validate you (or your customer) have the authority to originate the prefix? I understand there comes a point where a T1 network has to accept any route that is advertised to it, however, ROAs (and ASPA when it becomes mainstream) I believe can help secure routing, even at a T1 level.
