Would there be any practical way to provide them with some simple markup that allowed marking up their designs such that some sort of scaffolding tool could be used to convert it into a starter project for vario…

I was guessing '7%' performance rating but did not expect to have to reboot! If you run the same audit tools on any Wix website you can expect the same sort of nonsense, maybe a megabyte of scripts at the top, CSS where it runs to 10000 lines of which 97% unused, images flagged for being b…
Secondly, if there were an easy way for designers who are not extremely technical to attribute their code, it actually could greatly help some of the problems you're referring to. For example, if a pre-processor knew what the intent was it could replaced a bad or bloated decision automatically without changing the semantic meaning.
Finally, as for the suggestion around keeping it simple with basic constructs and are predictable and easy to work with, there is no reason that couldn't be part of some type of effort like this that attempted to extract more value from artists than their technical knowledge may allow and realize the potential of many more designs.
