That's like refusing a fresh cheeseburger because you're afraid that by the time you bite into it, it'll develop botulism - even as you're minutes away from starving to death. You're nitpicking tiny details and dismissing a clear improvement because it does not conform perfectly to your idealized standards. Life is messy, people make mistakes. That just means we keep moving forward and self correcting when we need to not when we make up entirely hypothetical downsides, most of which never end up happening anyway. I repeat, again: you have provided zero evidence for your claims that the Rust team is doing the wrong thing or heading in the wrong direction.

This insistence on using hypotheticals instead of providing evidence screams fear; not a rational evaluation of the community and its plans. It's the same tired strategy used by conservatives for thousands of years to fight literacy, education, suffrage, abolition of slavery, welfare, universal healthcare, and pretty much everything good that has happened in human society. No one but its rhetorical peddlers take it seriously because it is purely self defeating: if you're too paralyzed by hypothetical issues to take the first step, then those issues will never be resolved, freeing you from facing the uncomfortable change ahead.
