Remove puck
All this risk involved with potential fire is a fault on valves part, but i think people really should just remove the puck from power when not charging or using the SC.
It's not a good solution, and valve should fix it, but why risk it? It's not like it can wake up the pc/steam deck, etc in the first place, so you would still have to get up to turn it on.
Otherwise, maybe a wall mount for it could work to keep it away from all the potential clutter.
