Small update on that thread, we ended up compiling our lib with 1.7 and languageVersion=1.6 but it looks like languageVersion doesn't work for native/JS so that forces every native/JS compiler into 1.7. Upgrading should be possible for consumers in most cases but definitely something to be aware of.
