I just downloaded and tried out Steam Link only to find that my Joy-Con don't combine into one controller, I suggest that Steam Link have the option to combine them. I'd think it wouldn't be too much effort to port the code in Steam that does that to Steam Link, or even passthough the Joy-Con and let Steam do it. If it is supposed to do that, it's not working for me.

Separate thing, the Left Joy-Con's face buttons are unresponsive on Steam Link, this feels more like a bug.
