I'd wager the demoscene is pretty conservative to begin with. All the comporules and jargon derive from the Warez/cracker scene in the late eighties and haven't really changed much since - only the capabilities of the hardware has. Eg: an "intro" means a demo made against a size limit. It's called an intro because cracked games were spread with little introductory animations (sine-scrollers, chiptunes, you know the drill) by the cracking groups. These couldn't take too much space lest the game got too big to easily distribute. Then, people started making intros without having a game to distribute them with, and the rest is history. But that's >30 years ago now and we still use the same term and the same size limits (4k, 64k) as back then.
