Umami is primarily useful for provisioning of "multi-VM" applications, which is what the SecureDrop Workstation example would deal with. It could also be used relatively easily by a graphical application that reports on screen what the example reports on in a terminal.
However it may also be used for multi-VM app migrations under certain circumstances, or even just as a more consistent qubesadmin API.
It would be good to expand on all those things, as well as justify its existence by comparing it to other options.
