Why are there Sol Divisive supplicants in the updated Inverted Spire?

It's just a small thing but it kinda takes me out of the game. Why would Sol Divisive supplicants be operating alongside the Compelled Vex? I can get behind Protheon still being the strike boss - adding a yoke to their model would probably be in the too hard basket - but not mixing subtypes like that without some kind of story justification.

It's just a lil disappointing to see the lack of attention to detail. They clearly had Oded Fehr around to do a new Osiris line for the strike, so they could have at least lampshaded the subtype mixing (it's exactly the kind of thing Osiris would comment on).

Oh well.
