No because the Legion writer had a perfect out with LSH vol 3 #18 and they did not use it - ever.
What is this perfect out? I'm not all that up on my Legion lore.
It was a story in which the Infinate Man was holding back the changes Crisis caused. Once defeated history was to change to fit the new timeline. Problem is the LSH writer never used this and kept going on as if nothing had happened which lead the the Pcoket Universe Kludge.
