Research direction
Start with the linked TPiL section on using the simplifier, then compare its guidance with Mathlib's treatment of commutativity and associativity. The issue does not name a file or proposed change; done would be a clear explanation of why these laws are not registered with simp, documented in the relevant learning material.
