wow - that's pretty awesome! What do you think about instead having a
ChromiumMultiDex.java.template and use jinja to conditionally elide the body?

I think the simplified build might be worth it?

Keep in mind that doing things this way is super easy with GN:

if (enable_multidex) {
  java_files += [...]
} else {
  java_files += [...]
}

Definitely worth it.
