After talking with the team, currently this is my error in the patch notes. It is intended that non-final bosses are dropping Prototype and Artifact gear (not unassembled, which is my error). However, given the feedback of this thread (and the one you linked) the team is looking at improving this experience in the future.
Apologies for the confusion. I will let you know of any potential changes to this in the future and I will get the patchnotes updated.

Thanks Eric, while that is dissapointing, I am hopeful for future changes.
