Sorry Mark, but my question was NOT related to WCS...

It's just a matrix, cube, hypercube or whatever n-dimensional hyper-rectangle.
And on my side I'm perfectly happy with whatever convention for denegerate

having a CDELTi = 0 for these degenerate axes, and was wondering why.

Sometimes I've found it necessary to tell fv to turn WCS off.
