Agree with this 100%. Apple touted Shortcuts on stage at WWDC for an extended amount of time and then proceeded to throw it out into the wild with very little in the way of evangelization, support, guidance in the way of tutorials and a user-friendly help system. The Workflow help text, which was largely adopted whole cloth by Apple was very good, but not easily searchable. It was much better suited for the power users who were the primary users of Workflow.
My guess is that the original plan was to release Shortcuts with IOS 13, but that the rapid adoption of Alexa and Google Home/Assistant forced Apple to rush it out the door to try to give Siri enough new features so they could claim parity on some level.
I have higher hopes for Shortcuts 3.0 which should sport much more polish, along with MacOS support.
