In fact, there's a hypothesis that the QC was the original burial chamber before the KC was added to the design and that the QC shafts DID extend to the "original" skin of a much smaller G1, but when there was a "change in plans" that required the KC to be added to the design, then through a variation of accretion more width and height was added to the masonry to accommodate the newer KC shafts. Pure speculation, but it accounts for some of that shaft geometry.

By the way, since there's been some talk of "reaction chamber" in this discussion, I just want to point out that "limestone power accumulation" was a typo. I meant "limestone powder accumulation"!
