First this was wrong for files written in 2.93 read into blender in 3.0 after the CyclesX merge. Then this was fixed by versioning in rB6321dd3d4007. But this caused files written in 3.0 to have this versioning applied as well (leading to socket shifting). Now only do the versioning for files created before the CyclesX merge.
