Nooooo! Don't make me INSTALL a standard-compliant shell!! Make me install a NON-standard-compliant shell.

It's better to have an old version of a standard-compliant shell be the default. Users can easily install the latest bash/zsh, but make that a personal choice.

The license isn't a valid reason to swap out bash.

I'm pretty sure bash still comes with the system. It's only the default shell which is easily configurable.
