No.
It's a guaranteed way to carbon-date your game when decades later someone decides to play it on their toaster at the pathetically low resolution of 8k and finds the game to be extraordinarily pixelated to high hell, even more than how 8k looks compared to 16k down sampling. And so he decides to flex his Titan Y (God knows why he hasn't upgraded to a Titan Z yet, the Y's a decade old) and play the game down sampled from 16k. Nope, game is still pixelated, with out of place clear objects standing out. Oh, what is that, a remaster/mod that has high resolution backgrounds? Oh they're just upscaled. Now it's blurry and lacking in definition, with tiling if it's an SE game.
3D environments aren't just the future, they're future-proof.
