constant expression make sense in C. It is not new, it is very old.

variables.

yes. but?
What I am suggesting again is remove the keyword constexpr. make const do that.
Just to remember C++ was already like that before constexpr. In c++ const could be used as constant expressions.
What C++ could not ensure is that global variables would have a compile time initialization.
In C all global variables are initialized in compile time.
For local variables like...
const int i = ... ;
the compiler must evaluate the initialization expression if it can be computed in compile time then i is "constexpr" does not matter if it have or not the constexpr keyword.
