I agree. I remember very few bugs caused by the rewrite, but I don't remember recent ones.
For example, I found a bug running the tests of the r7rs package, it was simplified to a bug in "plain" Racket and later fixed, 3 days after the initial report. It was in June 2019 https://github.com/racket/racket/issues/2675 Note that at that time, the default version of Racket was he old one (before the rewrite).
