Intel Publishes "X86-S" Specification For 64-bit Only Architecture
Intel quietly released a new whitepaper and specification for their proposal on "X86-S" as a 64-bit only x86 architecture. If their plans workout, in the years ahead we could see a revised 64-bit only x86 architecture.
Entitled "Envisioning a Simplified Intel Architecture", Intel engineers lay the case for a 64-bit mode-only architecture. Intel is still said to be investigating the 64-bit mode-only architecture that they also refer to as "x86S". Intel is hoping to solicit industry feedback while they continue to explore a 64-bit mode only ISA.
[...] Under this proposal, those wanting to run legacy 32-bit operating systems would have to rely on virtualization. To further clarify, 32-bit x86 user-space software would continue to work on modern 64-bit operating systems with X86-S.

If I rememberize correctfully from BYTE magazine and living in the late 1970s . . .
I think you mean legacy 8080 source compatibility.
The stupid segment registers of 8088/86 that were a thorn in the side of PCs for decades, were to have assembly language source code compatibility (but not binary compatibility) with 8080 if you could preset the segment registers correctly. What I would call a Pyrrhic victory.
