The benchmarks in this talk show that the bounds checks are mostly insignificant, and actually it's the integer overflow checks that are far more costly.

Actually nm, I forgot those are disabled in release mode. Good decision I guess.

Do they even count towards safety if they aren't in release mode?

You can enable them in release mode optionally. But I would say not. Really we need ISAs to provide a no-overhead way to check integer overflow.
