Probably smart if you need a controller in the immediate future. There's pretty much zero chance of anything LE related being released in the next couple of months at the very least.Well thank you for the response, I'm going to get an official wireless X360 controller with a PC adapter at $17 that also works with Syscon, I already have one but I don't have the adapter so I can use both on Switch or PC, not that it matters to you all that much.
I actually own a Ring Fit, the left Joycon shows as a single vertical controller and the right Joycon shows as a horizontal controller on the Switch menu, the Ringfit ring on the place where you connect the right joy-con has a chip and a flex sensor inside the plastic rail, it uses extra hardware in there to see how much stretching and bending you are doing to it, the right Joycon by itself couldn't detect that. I don't think that's something that could be implemented via Mission Control at all in my opinion.
Thanks for the info on the ringfit control. Sounds to me like it is just seeing the controllers as joycons, but is maybe using one of the extended reporting formats used for things like IR, NFC etc to receive additional data from the ring's sensors. This could of course be faked in response user input such as a button press or something, but I'm not sure if that could really work as a decent substitute. This also becomes more complicated if the controllers just appear as joycons, as we don't want to mess with inputs for regular controllers like that.
