[ttyprintk]

On Windows,

    mv s:\src d:\dest

Works as you expect. Now on some unimportant directory try:

    mv s:\src

I have to think hard about an equivalently-stressful typo on another interactive shell.

well this is a critic of this one command, but how is it a critic of data oriented shells?

[ttyprintk]

I'm probably just cranky. Moving files is a universal use-case, i.e. xargs predates Bourne. Maybe PowerShell hasn't arrived at the amount of reliability testing we expect from a data utility. If I saw it being used as such, I would ask for many assertions for both data manipulation and filesystem traversal.

for the record

  mv C:/folder 

will only delete if folder is empty

[ttyprintk]

I suppose in POSIX:

    sudo ifdown ens1 ; ifup ens1

But this one is easier to understand.

I think POSIX mv is terrifying enough. I've found it to be much more dangerous than dd or rm.
