In general I think the "ship fast and break things" mentality assumes a false dilemma, as if the alternative to shipping broken software is to not ship at all. If thats the mentality no wonder software sucks today. I'd rather teams shipped working, correct, and performant software even if it meant delaying additional features or shipping a constrained version of their vision. The minimalism of the software would probably end up being a net benefit instead of stuffing it full of half baked features anyways.
