Core makes sense to me, as a description of the entirety!

Actually, the old "backbone" was a mesh, with redundancy.  Some NSPs
claiming "backbone" (such as PSI) have so little redundancy that they
fall over regularly.  And the connectivity beteen many NSPs is excrable,
as well documented in this forum.

My point was there are few (if any) backbones.  If your own back didn't
connect to all your limbs, you would have a bit of trouble standing.
