Those are orange vs apple, just like the rate of rollbacks

They compare something new, which rewrite existing stuff (not only but still) with some decades-years-old cruft

In they new code, they know what they want

They can also start with state-of-the-art unit testing that may not exist in the early 2000

So .. yeah, those numbers ..

That rust is saner than c++ is a given anyway :)
