> The touch controls on the Steam Controller are excellent though, so I'm not sure how good it will be on the Switch which uses joysticks...

Whilst lots of games ignore it, the Switch screen is a touchscreen.

You kinda have to ignore it if you want your game to be playable docked.

I happen to be one of those switch users who almost exclusively use it docked. Initially I thought the concept was great, but the screen is just too small for my eyes on all the strategy games I play, I always defer to my iPad on holidays.

I actually purchased multiple docks, the nice thing about the switch to me is being able to quickly move it to another room as needs arise.

Plenty of games have multiple sets of controls. A handful of Switch games make use of both, to great effect. Like Cozy Grove. You don't have to completely ignore it, to allow for one playing style.
