I'm in the camp of "that would be awesome!" but certainly not something I need. There are a lot of cool features that would be awesome, but not required. Witcher 3, for example, has graphical settings on the Switch version - I don't think it'll be a situation where Switch 1 software is locked into Switch 1 power - it'll be running on the updated SOC (I'm assuming).
I do want to play a more beautiful version of Witcher 3 on my Switch. Graphical settings are already a thing on the Switch version of Witcher 3, it'd just be a matter of adding in a "Switch 2" setting and running a check to make sure it's compatible on the current hardware.
Really, the main thing I want is true backward compatibility (not something like Wii Mode, where it is something separate; but, have Switch libraries integrated into Switch 2) so I can continue my library going forward rather than having it fragmented and locked to old hardware.
I describe myself as a little dose of toxic masculinity.
