I wonder if this will lead to fun bugs only manifesting when not debugging.

Improved code generation in the CPython JIT

100% guaranteed. But then these bugs wouldn't be bugs in your program, but bugs in JIT-compiler.

That means that Joe Average would maybe see them once in a lifetime, but there would some some people who would deal with them routinely, because it's their job.

Not any different from Java JIT, or C# JIT or any other advanced JIT.
