Been watching some videos on razor honing and repair, and when the topic of removing chips comes up, they suggest taping the spine to prevent its being worn down.

This would obviously deepen the angle of razor's edge. Wouldn't this be a bad thing? I mean other than trying to make the razor look less worn than it is, what's the benefit of preventing the spine from being worn down at the same rate as the edge that outweighs the desire to maintain the razor's designed edge angle?
