In my experience the requirement is driven by insurance and legal considerations; technical concerns are secondary. With "pop-up" sprinkler heads, PVC pipes and uncharged systems (until an alarm event) I don't think they have the negative impact on the room grounding and anechoic properties they once had. I think the major impact these days is simply cost.
A long time ago the driving need for sprinklers was the inflammability of traditional pyramidal foam cone absorbers. If a chamber just used ferrite lining, I think the fire hazard would much less. If you use hybrid absorber with tiles and foam cones, the problem comes back. Now there are newer forms of hybrid using tiles and what looks to be carbon-impregnated cardboard, which is likely also a fire hazard but not as much material to sustain a blaze. My chamber complex has no sprinklers. But it is homemade screen rooms, no absorber panels...
