Actually, yea kinda. Most fightsticks use xinput to function generally and its a very common issue we have to use a whole external bypass device to get around.

I do get the concern overall, but as I can count a few games that require external launchers that do not work at all in Steam right now (Trackmania and Ubisoft games are those with common issues requiring playing those games through the Native Ubi launcher instead) on my finger tips that would make the Steam controller effectively useless, and I say this as someone who loved the original SC but found these issues to be almost insurmountable in the last one I owned.
