About 7 or 8 years ago I used to optimize for the 5%. I remember thinking exactly what you wrote about customizing your shell. Back then I wouldn't even use aliases because "what if the server I'm on doesn't have it". Such a silly way of thinking but it made so much sense back then. Now I have tons of customizations in the environment I spend 95% of my time and it's way better.
