 Sure, most language features are strictly unnecessary.
 

Anything you do with it could/should be done with const.

 No, absolutely not.
 

If not, do you have a sample where, using "const" as "constexpr", would create problems?
The sample I know is VLA.
const int c = 2;
int a[c]; //a is VLA because c is not a constant expression.
But this is not enough to convince me because it is better not to be a VLA here.
