I agree with you that the vector semantics aren't a problem per se.  The invariant that stems from the initialization semantic keeps the interface nice and simple.  The question is: how should one program algorithms that need deferred initialization of elements?  If vector is to be the end all and do all dynamic array type, replacing VLAs et al., it needs to answer this question.  Could you elaborate on what you have in mind?
