The other bit is that if you really really want high reliability, memory
mirroring is the way to go; it is the only way you will be able to
hotremove memory without having to have a pre-event to migrate the
memory away from the affected node before the memory is offlined.

Some platforms don't support cross-node mirrors ... but we still want to
be able to remove a node.

Yes, well, those platforms don't support that degree of "really really
high reliability", since the unannounced failure of the node controller
will bring down the system.
