I'm not judging it but my experience is that the more dramatic a change, the more work it makes for IT. And on my site, I am IT. Just look at the mad scramble to fix add-ons after the changes in 2.3 (which had little impact on me, thank God). And that was not actually a big change, even though it was a breaking one for add-on builders. Just think what 3.0's overhaul of styling is going to be like. So changes like that require thought and care, not just "oo, shiny. Let's do it."
I love to see "quality of life" features for sure, but they are only improvements if they don't cause more work through bad design or broken implementation. So, I say it again, take the time to give me a few well-done, tested features rather than rushing out half-baked ones to meet perceived demand. IME, the software industry has become obsessed with pumping out "kewl nu featurez" rather than putting out useful ones. I would rather see XF buck that trend.
