What's "worse" about it? I think it actually makes sense.

The reason normal asserts are not put in release mode is for performance 
reasons: so that the program doesn't waste time processing the assert 
condition, when it could evaluate to true, and not generate an exception.
But when a program reaches an assert(false) it would always throw, and 
you have a bug, so I see no reason for it to be removed in release code. 
Unless you want your program to try to keeping going nonetheless 
(instead of throwing), but I'm not sure that's a good idea, although I 
guess it could work in some cases.
