I think we need to be more specific, since on x86 64bit instructions are a superset of 32bit. On ARM they are different with AArch32 and AArch64 being two separate set of instructions. It is AArch32 that is being dropped and no longer required.

They’re mostly a superset, but also some instructions were dropped like the bcd opcodes.
