The thing about gaming is that it’s not acceptable to leave 5% performance on the table whereas for other uses it usually is.

Right, you don't want two devices (that's fair). How can you _possibly_ trust the locked down device won't interfere with the other open software it's installed side by side with?
Also you can plug a mouse in a console… that's a weird excuse.
I think that’s an incredibly rare stance not held by the vast majority of gamers, including competitive ones.
That would mean those who are concerned about the integrity would want to sandbox everything else instead. And even if people are ok with giving up a small bit of perf when gaming, I’m sure they’re even more happy to give up perf when doing online banking.
The security of PCs is still poor. Even if you had every available security feature right now it's not enough for the game to be safe. We still need to wait for PCs to catch up with the state of the art, then we have to wait 5+ years for devices to make it into the wild to have a big enough market share to make targeting them to be commercially viable.
