Error when defering `cmake_policy(POP)`

Given the following snippet:

cmake_minimum_required(VERSION 3.21)
project(policy)

cmake_policy(PUSH)
cmake_language(DEFER CALL cmake_policy POP)

CMake will complain

CMake Error at CMakeLists.txt:5 (cmake_policy):
  cmake_policy POP without matching PUSH
Call Stack (most recent call first):
  CMakeLists.txt:DEFERRED


CMake Error in CMakeLists.txt:
  cmake_policy PUSH without matching POP

However, I think this is counter intuitive and making it work is more useful than the current behavior.
