Google Closure simple optimizations only?

[hlship]

Why are we limited to simple-level optimizations only?

I was thinking about this recently. Basically, changing from simple to something else would break backward compatibility.

However, I think what this needs to look like is a list of compressions we want to do: :closure-simple, :closure-advanced, :css-whitespace, :less, :uglifyjs, etc.

What do you think? Any interest in making a patch?

and can you add extern file support, @pbiggar ?
