More programming in the world is done in a 1-based language, Excel, which has more users than all other languages combined. 0-based languages are in the minority as far as installed base and usage goes. Being 1-based is a decision dependent on target audience and application. Fortran, one of the earliest languages, is 1-based, so there’s plenty of historical precedent. Matlab, one of the most commercially successful languages in history is 1-based, so it’s not exactly a barrier to adoption.
