The VM is not built for every release, it is copied into the release. The fact that it isn't built for each release is why cross-compilation of releases is not possible.

I must be an idiot because I still don't get it. If the VM is just copied into the release, not built, why can't you do that on macOS for deployment on Linux by copying a Linux version in? Why do you need to do it in a VM or Linux build server?

[gamache]

It's probably only that no one's written the tooling for that yet, because it's easy enough to set up a Linux VM or build server.

The tools (relx, exrm) can do that.
