The team wanted to add a fight scene in a bar that, try as they might, always put them over the 40 megabyte limit on the Wii build. Eventually they gave up and made it an exclusive club that you weren't allowed to go in and had the fight happen off camera. They named the bar "Club 41."

In summary, I don't think the art of handheld[5] demakes is at all lost.

Along the same lines, there's also the "fantasy console" Pico-8[1], which is designed to mimic the limitations of old handhelds, but with some modern development improvements. It features a number of de-makes, including Street Fighter[2], DOOM[3], and OutRun[4], which can be played in a browser.

The same applied to the original gameboy. In fact only the Gameboy Advance SP and maybe the DS Lite were small enough to fit in a kid's pocket.
The Nintendo Switch came out in 2017, and remains quite popular.
You aren't seeing many DS series devices around anymore because it's quite old at this point -- the last major product in the line (New Nintendo 3DS) was released in 2014.
