Well, yes, but so does the current code. 

Sure, in _theory_ it can be a non-mmap executable (maybe people still have 
those old OMAGIC a.out executables), and in _theory_ you could unmap the 
executable even if it was originally mmap'ed, but neither of those is 
exactly common, are they?

So in practice, nothing has changed wrt lifetime of the executable.
