Previously, creating and consuming resources in an internationalisable way has been - maybe not difficult, but definitely a bit painful and a lot of work.
Today, I created a handful of new resources and a couple of new resource files in side projects, including appropriate accessor classes in under ten minutes. I also scrapped our own pre-existing classes for doing the same job. They were good enough, but not quite as flexible as the autogenerated classes can be.
It's always satisfying to be able to reduce the amount of code we directly write and maintain.
