Qcow2 option for composing KVM VMs

Hey folks, where are you on adding the option (or changing the default) of using qcow2 instead of raw for KVM VMs?

Last post here in 2018 and later this bug was filed in 2019, but no action since then.

This has been bothering me for a long time also…

I worked around it letting MaaS commission the VM, and prior to deploy I manually run qemu-img convert, and also change the VM disk type to qcow2 on the virsh host.
