It seems like a missed opportunity not to have a JSON (or other explicitly machine readable format) output option for easy scripting use through jq. Every time I need to craft a grep regex to get some trivial piece of information from one of these tools, I feel there's a bug waiting to happen (and I'm usually right).
In what capacity is Powershell something other than just another shell (of your choice)? Feela like Windows finally got a real CLI for API stuff - and O am glad this happened - but it's not really any different than csh, bash, zsh et cetera. A shell as a lower-level interface to your OS.
