Based on the (limited) benchmarks I've seen, we'd pay a price in terms of build time and size (both worse than the Java version).
These are not for "advanced compilation", but interesting to see the comparisons with Babili here: https://github.com/babel/babili#benchmarks For non-advanced compilation, Babili and Uglify are significantly faster than Closure Compiler (Java). And both get close to the same build size. The Closure JS Compiler doesn't look worth consideration in this case. If advanced compilation sizes were comparable (between the Java and JS Compiler), I think dropping the Java dependency would be worth the extra build time. I'm hopeful that when we're free of the Closure Library and have an option to build the library together with applications using more mainstream Node based tools, the convenience will outweigh the benefits of advanced compilation with Closure Compiler for most users. The promise of advanced compilation with the Compiler sucked us in but made it very inconvenient for many people to use the library - people who I imagine are now using the full build while only requiring a small subset of it, negating the benefits of advanced compilation.
