Sonoma adds the ability to suspend a virtual machine and it does appear to have some enhancement in screen sizing. But it still doesn't allow:

• virtual machine snapshots
• resizing a virtual disk after it's created
• USB device connectivity
• Signing in with your Apple ID to the virtual machine.
• Running of more than 2 macOS VMs.

It's also been reported by others that its virtual disk I/O is smoewhat slow - slower than you'd expect even when running on a SSD.
