I think it would be perfectly sane for a company to dictate which scripting language their environment will support. Shell scripts are a bit different though because if you write a large enough software system on a unix-like OS you'll probably want to write a few shell scripts here and there to glue things together, so forbidding them completely would be a bit silly and counterproductive. Saying "avoid shell scripts, if you really have to write one it must be simple and use POSIX sh" is not particularly insane to me. But anyway my argument was more about my opinion about a developer talking for myself, not a company style guide. Life's too short to learn two shell dialects so I can either learn POSIX which will work basically everywhere and will let me write any simple script just fine or write Bash whose added complexity I probably won't need or even want. The fact that I'm an embedded dev probably biases my view though, I generally target environments where bash isn't an option anyway.
