Zenbleed's impact is due to userspace (including library) use of AVX registers. Glibc is part of userspace. OpenBSD libc is not glibc. It's a valid difference.

I don't think this is an example of foresight / good design choice, though. They just got lucky that no one cared enough to do performance optimization on their libc string functions.
