Pretty much. Yes.

I want the VM to survive my logout.

wouldn't starting the VM in headless mode net you the same results?  The
only difference there being when you wanted to do 'GUI' related work you
would have to connect via VRDP.  All my VMs run headless on multiple
servers (SuSE, OS X, etc) and I connect via VRDP using a web client and/or
a RDP client (I use CoRD).

VRDP does introduce a number of challenges since features like drag-n-drop
and seamless desktop among others would no longer be available.

The GUI offers many ways to configure and interact with the VM (like
resizing the screen etc.). The feature would also allow users not to have
to decide in advance whether a given VM should run headless or not.
