That's the thing though. There are very few "actual workflows" in many people's lives (especially if you exclude their job), and many many "one off (few off) workflow". That's the magic.

So many tasks I need to do once, or just a few times ever, but they build up. While I'm not sure I'd use it for immigration forms specifically, that's the kind of task that's tedious and done rarely, so a dedicated tool doesn't help because who would be familiar with that tool and have it handy?

Let the minions create scripts for you.
