As a counter to your points, I think no-code works best if your business's competitive advantage is the non-technical side of things, e.g services, network effects, people, non-software products, etc. An example of such a business would be say an art dealer who wants to build a customized painting browser app for their clients, or a developer specializing in eco friendly materials wanting to showcase their materials. In such cases, no-code helps immensely because you don't have to spend much on engineering and you can iterate quickly.

Ideally, no-code providers should provide a webhook and a REST interface, and just be the best at what they're doing, instead of being a one-stop shop that tries to cover every use case.

If you want to cover everybody's usecase, build a better Zapier instead.
