An investigation will be needed to determine whether a policy
is needed to add this to the if() command to avoid possible
behavior changes for existing callers.

For reference, you asked this previously:

I've almost never needed to test the length of a list in CMake
code.  It's not very common in my experience.  What is your
customer trying to do?
