Kernel Changes Draw Concern
I don't know why this is such a big surprise. More features = more complexity = more likely to fail or go slower. And all the people who suggest that people recompile their kernels to get their version running in a state they want... yeah good luck with that. A: You may not even know what a given feature does B: it's unlikely you will know what apps in the future will depend on something that you stripped out C: 90% of Linux users will not know to do that by default or to improve their performance D: 99.9999% of computers have no idea what the fuck you're talking about.
