There's a chance that I can get by without missing it. I'm assuming it brings easier account mobility which doesn't affect me, and I don't do any online multiplayer (granted that's partially because my home internet is shit). I don't need monthly loans of NES/SNES games as I'm getting a NES Classic and will get the inevitable SNES Classic. I would like game transferability, or being able to buy a game on one console and having it available on all my consoles along with the save - even if the game is not free, I rather not have to rebuy the game at full price.
Of course if the price is something small like $60 a YEAR then I'll be okay with it.
