Qualcomm pitched Znew quite a while ago. It mostly ditched 16-bit instructions and added a bunch of instructions that were basically ripped straight from ARM64.

The idea was obviously an attempt at making it as easy as possible to replace ARM with RISC-V without having to rework much of the core.

An attempt that failed miserably. (it was formally rejected a year ago)

But, by now, it is expected that Qualcomm's RISC-V designs have been re-aligned to match the reality that Qualcomm does not control the standard.

Actually, it was an attempt to reuse as much of the ARM design they got when they bought Nuvia moving to a different CPU architecture. They were worried about ASIC design not software code.
