Real talk is that it's literally not worth it to program.
Short races are harder to build a scene around and are less popular than full sized ones.
Most players just tend not to play short races much.
Dwarves and Goblins are the 2 most popular short races, shortly followed by Gnomes for their fey ancestry and pointy ears, while halflings are usually dead last, halflings are a niche race that lets people fulfill their hobbit LOTR fantasies.
