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.
