The passage around this formula
…without discarding a single degree of freedom, it would be reporting an artifact of notation as if it were physics, and the diagnosis this article exists to enable would be worthless from the first page. Requiring to vanish identically under passive relabeling, and confirming that it does, is the covariance check every candidate in this literature has to survive before its behavior under a genuine coarse-graining is worth trusting at all.
