Personally, I’m just not into that solo game dev career anymore, been there done that. It’d basically require for me to start up my own business again, thanks to Finnish laws. Good point about the steam keys, hadn’t thought about those at all :–)
I have no solid plans for a game specifically designed for the Deck yet, but I’m really into local multiplayer games, and do think a game that you play on a shared Deck might be cool. For example a game with just joystick controls - one stick for each player. My background is in making local multiplayer mobile games and I feel the same kind of games would work just fine on a Steam Deck, too, with the hardware controls adding new possibilities for designs.
Cool! I had a hunch there’d be Deck users like you :–)
