> On a side note, if some bored person out there wants to make a huge splash in the CSS community, figuring out a way to target a specific DOM element, create the equivalent of an AST and specify a "dictionary", which would be a utility-css framework (tailwind, tachyons, basecss, etc) and finally reimplement the targeted DOM element in the chosen framework would be amazing.

This is quite doable for us at Protoship (we've built both a design-to-Tailwind CSS+HTML converter as well as a webpage-to-Sketch Chrome extension). It is a very appealing idea - to be able to recast any webpage into a Utility CSS framework, but I'm curious to hear about situations where it would've been useful in commercial work.
