Google is doing it all the time; it's not a question of money, it's that most developers don't want to work on old stuff they had minimal input on; it's easier to motivate with "hey, let's do new stuff" instead of "hey, fix these convoluted bugs original author wasn't able/willing to".

Yes, this is creating lot of churn in terms of apps and user interfaces. Developers as I said before are motivated to build new things causing adverse problems like this situation here were perfectly good apps are being rewritten to an inferior state.
