Don't worry, it's a phase. You'll go back to configuring at some point, just more judiciously. And then you go back to "Vanilla install ONLY!". And then you start to tinker again, just even more carefully. At least that's my experience over the last 20+ years. You need - for all the reasons outlined - the ability to work on stock systems, because you never know if you'll have all your favorite tools. At the same time, some things improve productivity well enough that they're worth adding to your dotfiles, so you'll have them on the machines that you spend 90% of your time on. (I'm thinking "127.0.0.1 ycombinator.com" might be a great one ;)
