The issue isn't whether the concept applies or not.

It's "What do you mean by 'sphere-at-the-limit'?"

And, remember, you'll have to deal with the notion of vertex of a
sphere---not to mention edge and face, before you convince anyone that
you're doing anything but demonstrating that you don't have a good,
mathematical, handle on these notions.
