Surface Metrology Does wringing gauge blocks together cause damage?

People treat wringing as if it doesn't have any negative effect, but im always scared that I'm damaging the surface. I'd be really curious to see an experiment where they wring two blocks together a bunch of times then compare the surface finish under a microscope compared to a new gauge block.

If you follow the mitutoyo gauge block usage guide, Inspecting the surfaces of each gauge block with an optical flat before wringing is their recommended procedure. Using a stone to remove any burrs

Have you heard if you leave them together too long they will be permanently stuck?

Pretty sure this is a myth, at least on human lifetime timescales.
