I'm curious whether or not an embedded Esprima AST parser would provide a decent API for writing rules that detect undesirable code and rewrites them as no-ops.

I'm curious whether or not an embedded Esprima AST parser would provide a decent API for writing rules that detect undesirable code and rewrites them as no-ops. It would be nice if this was also a social version of user scripts where I could visit all the user scripts that other users wrote that work on the page I am currently on. A button in the browser that takes me to all the user scripts that match the URL pattern for that page would be awesome.
