I think that was always the case. actix is a singularly unique example, and I had never seen anything like it before or since. Not even close. There just hasn't been any Rust project with that kind of popularity that also contained egregiously unsound code. So we're not just talking about unnecessary use of unsafe here, but egregiously unsound usage of unsafe.
The attitude toward 'unsafe' has pretty much always been the same. Use it. It exists for a reason. But make sure it's justified and strive for soundness.
