With public peering you simply never know how much spare capacity your peer has free.
So with your key peers you talk to them and find out, but I don't see how this is any different if you have a private interconnect. Just because you have say a STM-1 into another peer doesn't mean they have the STM-1 to carry the traffic out, given your example below I'd say its even more unlikely.
And would you expect your peer with 400 Mbit/s total to have 400 reserved on his AMSIX port for you when you see 300 at LINX and LINX goes down?
Key ones, yes.
Been there, numerous times. I still tend to say - it depends on your type of peers and traffic per peer.
But your point on public versus private doesn't alter those facts.
