It would be "nice" (this is an Enhancement, not a Bug) if an Augmentable DataObject would have an alternative sugar shortcut new addAugmentation method variant which does not require the first (java.lang.Class<? extends Augmentation<...>> augmentationType but only the second Augmentation<...> augmentation argument.

This would just shorten the typical and often found code which IMHO is a little a silly, where the interface of an augmentation has to be specified together with creating ("can't it figure this out by itself??" - kind of thing).
