Speaking as someone who is still maintaining a web forms app, that sounds like a people problem, not a tech problem. You can implement literally any workflow if you understand continuations, and it will be simpler and more lightweight than web forms.

If you don't understand continuations, then you'll struggle and invent all sorts of poor state management patterns. Web forms simplifies some of this because the continuation is captured in viewstate, but it captures too much state (there are other warts too of course).
