They can also introduce Windows/DirectX APIs that Proton will have a hard time copying, by requiring additional hardware or subsystem features not easily copyable.
They can let their legal team have some fun.
Finally, companies don't last forever, and I am betting as the 2nd most valuable company in the planet, Microsoft will outlive Steam's current management and eventually deal with the problem in another way.
Steamdeck is already a niche device, and they have direct competition since years now. Optimizing the software and interface won't probably make it much worse for Valve.

Seems unrealistic that games will adapt a new restricted API, which at the same will be a longterm hazzle for Wine/Proton, and will survive that court-battles. At best, it's just some annoying money-sink, with Microsoft playing on time to make it worse for everyone without gaining any real advantage.

That's actually realistic, but there is also the chance that valve will be outliving Windows and has to battle with whatever will follow.
How so? A console is literally a gaming PC.
I can see the point of “need multiple consoles because game X isn’t on console Y” or “I’d like to play an RTS/MMO that isn’t on a console” but since you mentioned gamepads that point mostly dies.
I also haven’t ever had a PS5 or Switch controller lose link from a console because someone walks or stands between myself and the console.
Consoles are walled gardens, while PC is an open park. On a proper PC, you can choose anything from everything, while consoles are very restricted in terms of software and ability. I mean, think about modding, running other software besides the game (browser, (voice-)chat, etc.), having special hardware like a mouse, keyboard, capture-card, a second screen... Consoles are again slowly those things, but it's still not the same as a proper Gaming-PC.
