Topic on Talk:ResourceLoader/Package files

It's now explicitly documented that you can't do this.

Is it possible to have a RL module that defines both files and packageFiles. e.g. are they additive ?

No. I should document this more clearly: if you use packageFiles, you cannot use scripts, languageScripts, or any of the other *scripts properties. You can define CSS files of course (in the *styles properties).

...I should also add that if you do try to do this, you will get an exception at definition time, telling you that the two properties are mutually exclusive
