hum, actually the wiki article at
https://pve.proxmox.com/wiki/Resize_disks says:
"Shrinking disks is not supported by the PVE API and has to be done
manually. "

there is nothing wrong with this approach.
the thing is that from the hypervisor size we have absolutely no way to
know if the prior FS shrinking operation completed successfully in the VM.

The risk that the user shoot himself in the foot is way too big,
especially if such an option lands in the gui.
