It is, and I think at least some (perhaps all) modern compilers will do that already.  However, a dead store could either be "this is part of an idiom, and some of the stuff done in the idiom isn't always useful", or it could be "somebody made a mistake" (typed the wrong variable name, deleted some code but forgot to delete other code that the code removal rendered unnecessary, etc.), so getting dead-store warnings can be useful.
