Ah, that's interesting, thanks for sharing. Their github README does a nice job of showing how it doesn't add a lot of work: https://github.com/Juniper/libxo
I think for the devops person or someone doing server administration (sysadmins etc) powershell everywhere must make things easier even with the trade offs (as some have mentioned, it does have a bigger memory foot print, which may or may not matter depending on a host of factors)
As a developer? I haven't found PowerShell more useful than zsh/bash or fish (if you haven't, try fish, it has a lot of benefits of PowerShell (fish has its own scripting language that is more "language like", like some of the more simple constructs of Python, syntax wise) but via a simple plugin[0] you get bash compatibility too, and its made for Unix like environments). I do like that it has a rich object data model, I just don't do that kind of thing in my shell. I mostly use aliases, shortcuts, and maybe some grepping. I don't do heavy duty tasks from the command line where I'm not writing the logic in the first place, and I just find it easier to use the standard that my team does (currently, this is JavaScript, with the shebang it executes just like a binary. We can reliably say everyone has the same version of node)
Maybe in the future this will change, but I don't see the win to divide my attention economy to it deeply, personally.

If you're working on a shared project where people might care, I usually have the [PSScriptAnalyzer][1] just auto-correct any aliases dynamically for me in my IDE.
If you're just doing a quick one-off or interactively, then who cares! Crack on with your incomprehensible one-liners!

The defaults come out of old CMD.EXE (bad) habits, so so yes are missing like a dozen years of Linux terminal UX experimentation/improvements.
One particularly common advice with Powershell is to try PSReadLine for more bash-like versions of tab completion and other line editing things: https://github.com/PowerShell/PSReadLine
As for common shortcuts, as mentioned elsewhere in this thread, Get-Alias (and Set-Alias) is a very useful tool.
`bash set -e`. Your examples don't work (if you have an answer please paste it in https://github.com/PowerShell/PowerShell/issues/3415 )
JFTR, stumbled over this recently: https://github.com/kellyjonbrazil/jc
Shameless plug - I created a cli tool called jtbl[0] that converts json output to tables in the terminal.
