I use n8n too, but the biggest problem for me (as a developer) is, that it cost too much time to define complex rules and test them. An easier define and better test output procedure could be a great advantage over n8n.

Don't concentrate too much on "non" developers, cause these people normaly not use such tools, no matter how easy they are. That is why i hope you add better tooling for developer, to make their live easier.
