We tend to care more about existing code than about implementations.

I am also not much impressed by arguments based on optimization.
But if we could make the language safer and more consistent,
I would support a change in this direction.

(For example, I am opposed to unstable values which are sometimes
proposed to enable optimizations. These would make the language
more difficult to analyze.)

Best,
