Great proposal! renaming to introspection is great for visibility. Most blockchain scanners support Diamond standard proxy but renaming diamondCut might take a while since a lot of projects built tooling with that selector in mind already.

@giuseppecrj Thank you for this feedback. I appreciate it. Instead of changing anything in ERC-2535 Diamonds, I decided to make a new standard: Proposal for a Simplified Standard for Diamond Contracts - #5 by mudgen
