In many compilers exceptions cost nothing in term of runtime. 
In some compilers exception specs cost a lot.

I don't know of any compilers for which exceptions specs 
cost nothing but empty specs help in term of runtime. Could 
you name one ?

I can't think of many real-world cases where non empty 
specs could help. For inline functions is doesn't help 
because the compiler would have as much info by performing 
inline substitution.
