Yeah, this is always the response. But it's wildly impractical - there are only so many developer hours available. The budget is limited, so not everyone gets what they want immediately. This should be obvious.
Part of the problem is that the novices that create these applications don't consider all the edge cases and gnarly non-golden-path situations, but the experienced devs do. So the novice slaps together something that does 95% of the job with 5% of the effort, but when it goes wrong the department calls in IT to fix it, and that means doing the rest of the 95% of the effort. The result is that IT is seen as being slow and bureaucratic, when in fact they're just doing the fecking job properly.
