It's great that POSIX sh is available everywhere except where it isn't (Windows). In all SW teams I've been in except one, sh was available, and people preferred writing things in something else (usually Python/Perl). I have had an order of magnitude more success convincing teammates to use just than convincing them to use sh. It may be ubiquitous, but it's useless if you can't convince non-shell gurus to use it.
