IIRC Xenoblade Chronicles and Fire Emblem Warriors were the only ones I really cared about. Lots of people held onto their old hardware; probably wasn't worth excluding them.

The biggest advantage of owning a New 3DS turned out to be the huge performance uplift. A fair number of games ran at double the framerate or only supported 3D mode on the newer hardware. Code Name STEAM had substantially less downtime on the New models because the AI could process turns faster. Several reviews for Hyrule Warriors Legends flat out said not to buy the game unless you had a "New" model due to performance issues.
