Honestly, this sounds bizarre to me. The idea that everyone likes the same things in a shell makes no sense to me.
I like a 2 line prompt (where am I, what context am I in). A lot of people don't like this at all.

It's not that config is impossible, but it tries very hard to make the defaults work for the largest subset of users possible. And then provides a much easier config experience than most shells, since if things are broken for you they should damn well be easy to fix!
All I do is "sudo apt install fish" and I'm good to go with the 100s of out-of-the-box improvements it has over bash.
