no. They definitely shouldn't.
One of the most powerful things Nintendo gains from being a console manufacturer is controlling whats on the platform so they can schedule and emphasize certain releases.
The last thing Nintendo wants is an open door for people to be able to stream loads of games from their PC to the Switch. It would massively damage their ability to do keynote deals in the future with third party devs too, because generally when Nintendo does make a deal with one (say Capcom / Monster Hunter), they give them a good release window that's not TOO crowded.
The streaming from PC concept would only work if Nintendo highly limited WHICH games you could stream to the Switch, which would ultimately pretty much defeat the purpose as the whole joy of the concept is being able to play like your STEAM library on the go on the Switch.
The only way it would be killer is if it was not controlled by the big N and a free app/program to use as you please. But that will never happen so I think it's a terrible idea.
anyway it takes control out of Nintendo's hands as far as deciding what's available to their userbase
