Always had one. But to be honest, prior to 64-bit and MEMLIMIT, it really was just there as an artificial limit for years. The systems I work on here and most of the ones I worked on since around 1998 were all large enough (and had enough aux storage defined) that one run away asid (the 'ol variable length getmain issue that everyone needed IEFUSI to protect) couldn't cause a problem. Even though I still have an artificial limit of 256M (our IEFUSI default), I opened it up years ago to give whatever someone asks for > 256M up to the entire private <2G. I still "penalize" all but STCs for REGION=0 by giving them our default region size of 256M in order to try and keep people from using REGION=0. Given what was initially done with MEMLIMIT defaults, I'm glad I did that.
