For the longest time I've been using this ol' Stadia pad. The Google Asst and Capture buttons laid dormant (I guess there is an open source program out there that can mess with these but I didn't want anything screwing with Steam Input potentially either.) When the support for the Xbox capture buttons went in I got access to one of the two buttons.

Not sure when it happened but I was playing a game with a fairly well thought out standard Xbox layout I didn't really need to change but wanted to throw something extra on Capture today. Imagine my surprise to go in and find out there's a spot for the other extra button now, it's fully usable!

Thanks for finally getting on that Valve. I'm sure it's some kind of side effect of the recent Hori and now 8bitdo extra button support but this is a good thing going forward in every way possible so kudos to you!
