I'm not going to knock the usefulness of the library, but I am going to knock its application. Architecturally, shell scripts should _exclusively_ be for bootstraps, configs, or extremely localized (individual developer) automation. The New York Minute you need non-trivial error-handling/flow-control it's no longer a "shell script" and deserves a proper rewrite in a proper programming language. Ian Malcom's quote from Jurassic Park comes to mind: "Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should."
