The new instruction may be a hardware implementation of this functionality.

See the latest POO for CSST's description. Specifically programming notes 2
and 4. (Note 2 admonishes one to avoid mixing PLO with Compare Swap
instructions for the same data structures, since they

I saw that.
The question was as to the need - what MVS (or VM or Linux) function has this
need?
