It's not OT to try to quantify, even roughly, how often __proto__ mutation matters (in static lines of code if not lines run at runtime per unit time). If __proto__ mutation is really rare compared to reading, and especially so if you exclude the "define" or "presetting not resetting" issue, then we should not linger on this too long.

We still need to serve the preset-proto use cases, for sure.
