> In my job, once an app is on the store it's too late, hundreds of thousands of people are going to be using it in the next 24 hours and you can't stop them or push a fix without at least a 24 hour delay in app review.

Yes, that's absolutely true -- I'm coming from the server side (mostly). On the client side, there are barriers to pushing that can't feasibly be removed -- in that case, it makes a lot more sense to hunker down and make sure every build is good; some users only rarely update for whatever reason, and you don't want them to be running a bad build for months (or to abandon your product because their first download was a bad build).
