Sometimes we end up having to use Powercli just to end up using other CLI via powercli itself (for example the ESX CLI).
It would be very useful to have powercli have access to see what those options and commands are available, rather than constantly having to look up EVERY command available in EVERY tree and EVERY single option and what they do
Unfortunately there are limitations to integration with other CLIs like ESXCLI. Hopefully some day you won't need ESXCLI and everything will be available in PowerCLI or through APIs!
I hope so
Its a massive headache otherwise
