That is way too much information for me personally (I am distracted enough as it is, and I believe real-time data like battery level belongs in your menu bar, not the terminal) but I can see how it would be useful to some.
That's amusing, because I've started liquidprompt for this very specific reason: I was constantly missing the battery notification icon. Time seems to have trained my brain not to look at this screen area. Fortunately, with liquidprompt alerts are spoting just where I look at, and only when necessary.
Yeah, Conky or similar status bar window manager widget is better for me for the real-time data (battery, cpu temp, date/time, etc.); too much to visually parse otherwise.
Definitely some nice features in here at first glance (colored directory perms and colored root vs. normal user are real nice-to-haves for example).
If you look under features configuration there's options for turning a lot of it off. I agree that the majority probably isn't useful unless you're running without a window manager for some reason, but even just the VCS info is pretty neat.
Window manager doesn't necessarily imply menubar. For example, with xmonad, you don't have a menubar unless you install xmobar. This could be an alternative to that, though admittedly that's a really obscure use case.
For me, most of this I don't want, and some I already have (git repo stuff), but some is new and potentially really convenient, especially the stuff for number of sleeping/background jobs.
