Well I'm still slightly on the fence since you did bring up some valid points (I knew I was missing something :P) with the Inquisition War Trilogy (which is a classic). The main problem arises from the fact that on the whole, Star Child lore hasn't been touched upon in close on twenty years, while other areas from that era have been significantly updated. The other problem comes with the "Perpetuals could be replacements for the Sensei" comes from the point where the Horus Heresy series is still developing to this day, and that while the concept of Perpetuals originates from Legion (back in 2008), there is still a lot left to be explained (particularly in light of more recent installments like Vulkan Lives and The Unremembered Empire).

My proposition would be to "mothball" Perpetuals and the Star Child lore until such time that there's more clarification. So not to delete current articles, perhaps namespacing or Archiving them until such time as we have a clearer outlook on what Perpetuals.
