Hasn't that already been tried (10+ years ago) with projects like https://github.com/jquery/esprima ? Which have since seen usage dramatically reduced for performance reasons.
Yeah, you are correct. But that means I have the benefit of ten years development in the web platform, as well as having hindsight on the earlier effort.
I would say the reason the perf costs feel bad there is that the abstraction was unsuccessful. Throughtput isn't all that big a deal for a parser at all if you only need to parse the parts of the code that have actually changed
