The net result is that adding const/immutable to a type can change the semantics of the program entirely at the whim of the compiler implementor.
C++ Standard allows the same increased precision, at the whim of the compiler implementor, as quoted to you earlier.
What your particular C++ compiler does is not relevant, as its behavior is not required by the Standard.
My proposal removes the "whim" by requiring 128 bit precision for CTFE.
