> 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?

If you're building macOS apps, it's common to want to test them on all system versions you support. Especially so considering Apple's attitude towards backwards compatibility.

And yet Monterey is EOL. Very few apps still support it. I wonder if it's just something that wasn't tested exactly for that reason.

EOL or no, there are many people who still use older OSes because they own older computers, can't afford an upgrade or don't want one (it works just fine!), and can't be bothered with figuring out running a newer OS on officially unsupported hardware.

Case in point: I built a macOS app that implements Google's Nearby/Quick Share (an AirDrop-style file sharing thing on Android). Multiple people tried running it on Catalina and were disappointed that it wanted a newer OS. So I did end up backporting it to Catalina.

Citation? I use Monterey at work and every app I need works on it still.
