I wouldn't call it a "drawback"; it's a *design* of the std::unique
algorithm. You're proposing a variation of it that doesn't eliminate the
equivalent elements in each run, it just moves them. That's completely
fine to propose if you have a use case for it! Just find a good name for
this variation (which is really the only thing I've been questioning),
properly define the semantics of what happens with the elements after
the first of each run, and create a suitable proposal.
