ZSH user here, with plenty of custom additions to it. For me it's not about building a parallel universe - it's about using tools at hand to make my life easier. Whether it be giving me information that I want, when/where I want it, or saving a few tens or dozens of keystrokes, it all comes down to the same thing. "What do you do when you have to use a computer without your customization? " I can't answer for other people, but when I am logging into other systems I am very seldom performing the same tasks that I do on my development workstation. I don't need those customizations because I'm not doing the kinds of things that require them. So when I log into another system, I just use it. I don't try to do the things that I can do on my local system - maintaining awareness of the differences is not a challenging thing.
