My experience is it hits both new-feature velocity and stability (or the balance between those two) really early, but lots of managers don't realize that this feature that's taking literal months could have been an afternoon with better choices earlier on (because they're not in a position to recognize those kinds of things). For that matter, a lot of (greener) developers probably don't recognize when the thing that's a whole-ass project for them could have been toggling a feature flag and setting a couple config entries in the correct daemon, with better architecture, because... they don't even know what sort of existing bulletproof daemon ought to be handling this thing that somehow, horrifically, ended up in their application layer.
So the blame never gets placed where it belongs, and the true cost of half-assed initial versions is never accounted for, nor is it generally appreciated just how soon the bill comes due (it's practically instantly, in many cases).
