The shell is API. Currently, if people write shell (#!/bin/sh) scripts
on Fedora, they can be sure that the same language is available on all
Fedora installations. If you suddenly make /bin/sh something that
might be different on all systems, you pretty much break API there.

In general, I am pretty sure that except a couple of programming
language or UNIX aficionades very few people can actually correctly
separate bashisms from true bourneshellisms.
