Have you stopped to think that maybe people will use this "experimental 3 month old language" for their personal stuff, and that not everything in programming is for your "whole team"?
Besides, "runs anywhere bash does" isn't really useful for a personal project. Work is where you're likely to run into a weird variety of legacy machines, not in a personal project where you have more control.
Regardless, the weird aversion to hearing advice that can just be disregarded if it doesn't apply to your case baffles me.
