Short of going back to the text based world, no. You'll never get the entire Open Source world to converge on one grand unified interface or toolkit. You'll always have at least one guy who thinks the way things are done sucks and takes advantage of the freedom the ecosystem grants to build his own path. And thank $DEITY for that guy, because without him nothing interesting would ever happen.
Me, I just tune out the silly bickering and focus on what I want to do with my system.
