Given its more ambitious goals and greater scope, Rust was always going to take a lot longer to mature than Go, so that there was no plausible chance of it reaching 1.0 before Go, if they started within a year or two of each other.

Except that on a different timeline really means Rust achieving 1.0 before Go, I didn't assert nothing else would have changed when they came to be in first place.

A different timeline is exactly that, a different line of events.
