It's fine for BASH versions above v3 and provides decent logging though I typically extend the script so that I can pipe long running commands into its logging framework. It also ensures that you specify the "help" options correctly as it parses the usage information to process the command line arguments with support for short and long options.
I think of it as a gateway to writing better scripts. When you first run it and it highlights what it considers to be a problem, you end up reading why it considers it to be a problem and that clues you in on some of the many footguns that Bash has.
