I just found a WIP Kodi port for the Switch on Github by a Team-Kodi Member velocity: https://github.com/VelocityRa/xbmc/tree/switch
I still wonder why this has not been brought up more frequently since Kodi pretty much does everything the community was asking for.
Don't expect a release date soon, it's very much a WIP.
FAQ:
Q: So what is Kodi? Sounds weird!
A: Kodi is an open-source media center, which is available for a lot of devices.
Q: What can it do?
A: It can play almost any media file on your device (which has been a much requested feature for the Switch btw). With the right Addons, you can also watch your favorite clips, series or movies on Netflix, Amazon Prime and YouTube (and much, much more)!
Q: How can I help?
A: You can tell the developer that there is a big enough demand for a switch port (Forum link). If you're a Switch developer you can help directly with the development since it's on Github.
Q: ETA?
A: Soon™.
You're not seeing much activity most likely because it's on every modern device known to mankind at this point.
