It's certainly possible it's just that I don't think it's as exciting an idea as people are making it out to be. And to the extent that it could work with a dongle it could also work with an iOS/Android/eShop app in the other direction with a docked Switch 2Absolutely, no "except" about it, though they figured out latency with Wii U, battery life and/or performance would suffer in reverse Wii U mode. I think it's unlikely but possible, if it does exist it's an entirely optional thing.
Worth noting that there's no shortage of Windows and Android based portables that do pretty much exactly this. One Type-C port wired for display output or connecting an external GPU and then a second which can just charge the device and is more conveniently placedThe supposed second USB-C port is seriously the most overthought detail right now. If there is one, it's so you can charge the console in tabletop mode. That's it. There could be other benefits like using USB-C headphones, but that would be the reason for its inclusion. The fact that the Switch can't be changed in tabletop mode is a notable rough spot in the hardware proposition (that multiple third-party stands, and one first-party, were created to solve). Nintendo could have easily decided to smooth it out.
With that said, having a high speed USB port available to use while you're docked? Maybe that opens up some options. Who knows. Although given the Switch's USB ports were rarely used outside of third party controller dongles and LAN adapters I'm not holding my breath. Not much it opens up that can't already be done on the Switch as it is really
