My 3 cents are that this isn't something that u get asked to put in from 
operators, it's something that is built in from the start. Just look at 
other workflow systems (which is really what nova/cinder/neutron... 
are); they don't try to add this functionality in later (or they 
shouldn't at least) but c'est la vie...

With that stated I would agree this is a community-wide goal (and a very 
very hard one since every single project 'forgot' to build this in from 
the start).

(another example of another projects UI that does something similar).
