What might help is if Apple had a browser based Shortcuts "app" in iCloud like there is for Notes, or Reminders. That way users could log in to iCloud and use a full size screen/desktop browser on a laptop or desktop to design, "test run", and debug (if needed) Shortcuts. The online Shortcuts app would have in context help and guided hints or more intuitive wizards that may not be possible in the iPhone based app. Then once known to work as desired, the user could "push" the Shortcut to your iPhone's Shortcut app or import via iCloud.
I'm like Pink and others above. Don't use Siri much (maybe I should), and even though I created a few Shortcuts (as posted earlier), I forget to use them. Perhaps because I did not see a way to get the Location logic to allow me to chose my home address, I'm subconsciously less inclined to create/use them, or because in my daily routines I'm not presented with a problem that requires solving with the Shortcuts app? (rhetorical questions for myself). And while I have taken programming courses, I promptly forgot most everything as I've not worked in developer roles. So maybe some consolation there as in my limited experience so far, getting the more complex Shortcuts designed, debugged, and working is probably not a "light switch" endeavor.
Back to the suggestion above, I'd also add an optional psuedocode or natural language/regular expression design step feature. That way if you sort of know what you want to do, but are not quite sure, then you can write out the "rough draft" actions and order of operations which could be coupled with or part of the debug feature.
