I'm not so sure people are "happy" with bash, given the complaints that keep returning, and that many aren't aware that zsh is actually different in this regard

I'm not so sure people are "happy" with bash, given the complaints that keep returning, and that many aren't aware that zsh is actually different in this regard. I also think the value of being the de-facto standard is somewhat overrated (as is the value of portability by the way); many scripts only run on one platform, one you control. zsh is not hard to install.
