It isn't uncommon that you prototype with a tool and it is super fast but before you can launch for real you need to rewrite everything.
At that point it is difficult to know if the prototype was valuable. Certainly quickly visualizing is good but a prototype tool that is non functional is even faster to use.
Having a tool that allows easy drag and drop without any friction on the generated code (including difficulty of using that code) while also having all the powers of HTML would be really cool.
Such a tool wouldn't be a beginner tool but any that fail this and can't really go all the way to final product gets discarded as "I am going to have to rewrite anyway".
Less of a "I am too good for that" more a "not a useful abstractions level" when considered holistically.
