1Tb/s per slot is a reality that will be here sooner than many might
realize.

I think the bonded vs. native argument can come down to optical bandwidth.
If you are limited to N number of wavelengths on a segment having faster
native interfaces becomes desirable (assuming similar optical bandwidth per
unit).
