I can remember the two of us being in a z/OS architecture talk at Share in 2004

It was something that sensibly had to be accommodated - no promises, but

architectural direction than HV common, but were eventually overruled by
Elpida and others within IBM who were dealing with the practicalities of
trying to convert existing code from 31-bit to 64-bit...
