These days, if I'm writing something in bash (or batch) it's often because there is nothing better available - like kicking off an installer, or some other wrapper / bootstrap script. For those kinds of simple tasks, the overhead of fully understanding the nuances of bash _and_ bash is way more trouble than the inconvenience of having fewer features available. This is not for bat/sh lovers, it's for those who have to use bat/sh even if they'd rather not. Having said that, I wouldn't use batsh myself until it does something sane with errors (at least the equivalent of `set -e` in bash).
