How permanent is marking a class API: public at this point? I have a CR that moves android out of backend and into contrib. But I need to mark

import_jars_mixin

public. I think I can convert the contrib.android plugin to not use it in a followup but this CR is already 10,000+ lines long or so. So can I mark is public in the move and add a TODO to convert the contrib module? cc @mammoth-pharmacist-54215
