I think a mistake by Nintendo because retro gaming is a big feature on any of todays consoles and always a money maker:

If you've been wondering when you will finally be able to enjoy Virtual Console games on the Switch, you might be in for some disappointment...

Answering to Kotaku, a Nintendo Spokesperson said that “there are currently no plans to bring classic games together under the Virtual Console banner as has been done on other Nintendo systems.”

“There are a variety of ways in which classic games from Nintendo and other publishers are made available on Nintendo Switch, such as through Nintendo Entertainment System – Nintendo Switch Online, Nintendo eShop or as packaged collections,” the Nintendo spokesperson added. “Nintendo Entertainment System – Nintendo Switch Online will provide a fun new way to experience classic NES games that will be different from the Virtual Console service, thanks to enhancements such as added online play, voice chat via the Nintendo Switch Online app and the various play modes of Nintendo Switch.”
