Partially yes, we still need to run the full suite of tests during 
development cycle so that we don't discover very late packaging issues.
But in a sense, it shouldn't be a blocker, as David pointed out, nearing 
GA, our packaging should be in a good shape, so installers bugs should 
not block us.
But it's only true if we pay attention to keep containers building and 
running using our packages during the whole cycle.
