Here's a nice example of the curve to index transpose in a well established codebase:

It greatly simplifies the job scheduler to cluster across index instead of some n-dimensional space when calculating placement in the cluster. Consider that each server in the cluster has multiple connections to other servers which all form a sort of hypercube with the Hilbert curve conceptually drawn inside it.

It also shows how simple the transpose operation can be. It's just a few loops and bit shifts.
