building a UI for developers is impossible, because every developer wants something totally different. it's also pointless because every developer will customize their environment to make it work for them.
you can't please all the people all the time. at some point you have to make a decision that some use cases can't be supported, for the sake of progress. in those cases, i think dropping support for the people who need support the least is the only logical way to go.
personally, i use ubuntu (and unity too!) every day as my primary development machine (python programming and database admin), and when i come home i have it on my primary play machine too. it does what it needs to do if you are willing to adjust your workflow a little bit. and if you aren't willing to adjust your workflow at all, ever, then maybe preconfigured DEs are not for you.
