The argument from 2014 is pretty weak. So what if it takes another reboot during deployment?
Better that than a BS manual process every time.
Also, systems migrated from my vmware envronment (via ASR) suffer from the temp drive forcibly taking "D" and re-lettering my migrated disks, which breaks pretty much everything when systems come up.
I've had to enforce the temp drive via DSC to ensure it doesn't reset itself at random after a reboot or some Azure LRS activity.
The ability to set the temp drive letter pre-deployment/migration would be a immense use to me and my team.
