According to what the link shows that is how shortcuts work. It's like anything else you do, a couple of times & you can do it w/o thinking.
I know when I receive a text, email, calendar, reminder alerts so I'm all good now.
Do you already have shortcuts? I'm assuming you do if you have the icons w/custom covers.
I don't think it's a work around. If you read any of those 2 sections there is some pretty neat stuff. You do have to think how the action will work but getting the hang of it I think you will realize you can use the shortcuts in a lot of ways. If you already have a shortcut for a icon or widget then it's just 2 more steps for the notifications.
