Honestly, the design aspect really wasn't something I had considered, It definitively does make a lot of sense. Still sad though that it didn't officially happen. So far, all the arguments I had seen against it where purely about the performance, which in my testing isn't really a big factor for this.
Doom is playable (albeit by reducing the viewport to a postage stamp) on a 386; I'd be curious how your patch works on the 386 considering how much worse the graphics performance is on it
