> It seems that M4 chips can’t virtualise any version of macOS before 13.4 Ventura

13.4 was released on May 18, 2023. That's actually not very far into the past.

Anyway, what would be the most common use cases for this? And how common are those?

CI is the big one, or similar testing against older versions for backwards compatibility. Usually good enough to just compile for it on MacOS, but sometimes we get a surprise in a third party library or something that only shows up on an older release.
