This question is closed because it's opinion based.

It basically asks why Ctrl + V paste is not implemented in PowerShell.

There's a comment below, "This can't really be answered by anyone except the PowerShell design team."

In my opinion, that doesn't mean a question should be closed.

For one, the PowerShell design team is also on the Internet; two, they might have written a blog post somewhere about it or put it somewhere in the specifications/RFC documentation; and three, there might be an obvious reason why it's not implemented.

I've seen many questions about why certain things are implemented in a certain way with good answers.

Examples:

• Why has Microsoft never implemented a loopback interface in Windows?
• What's the point of ASCII mode in FTP?
• Why was JavaScript implemented using prototypal inheritance?
• Why is std::map implemented as a red-black tree?
• Why is 'is' implemented as 'as'?
• Why is "import" implemented this way?

Even if people add opinionated answers, then the problem are the answers, not the question.
