Thanks, this explains:

The Windows NT POSIX subsystem did not provide the interactive user environment parts

So the interactive part, the shell itself, is not compliant. That is why I was confused

I am not a greybeard expert with deep bash history, but I though the posix compliant aspect of PowerShell was a very recent, though apparently not perfect, achievement even if "technically" NT was POSIX compliant by some specific definition in 1993.
