Ah, that does appear to be the same thing.

The policy only affects executables without exports, so it makes no
difference for anything that is getting CMAKE_EXE_EXPORTS_${lang}_FLAG.
However, the code path where the policy appears was already adding
redundant flags.
I think CMAKE_SHARED_LIBRARY_LINK_${lang}_FLAGS values in platform
files can be copied over to CMAKE_EXE_EXPORTS_${lang}_FLAG where they
are not set already. Then the policy's NEW behavior can be changed
to doing nothing because executables with exports will already have
the flags needed. The only reason to keep the old settings of
CMAKE_SHARED_LIBRARY_LINK_${lang}_FLAGS around is then to honor the
CMP0065 OLD behavior.
