Ask HN: Shell config is crazy complicated. Any solutions?

There are so many config files that are read in a particular order for each shell, interactive vs login, and for each platform. They all configure themselves using env vars and shell functions. Then every dev tool pastes some config into some of these config files.

It's really out of control.

The shell is probably the most used software on a developer's computer and it's a total mess.

Are there any solutions to this?
