There are certain fields and applications where this can be useful but at some level trade-offs have to be made and these trade-offs natural will limit the level of application.
As a professional plattform outside of agency and 'simple business needs' I think you will still need the option of a scripting language as plugins to keep the flexibility while focusing on your core case.
I don't know enough about your ideas, there are loads of cases where you could generate a workflow tooling that generates data structures and has certain business widgets. and this combined with a nice ML that 'guestimates' my needs can be really useful for a lot of people who don't want to be super technical.
These are some of my thoughts :)
