I'm willing to bet that most don't. For longer clubs, which is the more common adjustment, they'd have to take weight out anyway, not add it.Not correct. The better manufacturers add shaft weights or lead to the hosel to correct the difference in in swing weights.
I presume you mean the extender weighs about the same as the extra piece of shaft in a +1" shaft.
As said already changing to a different type of grip can change swing weight anyway.
