I recant my "you may be right".
After going back and inspecting the set up on my Raleigh Wyoming coaster brake, (it's been several years since I built it up) there is more than enough adjustability in the semi vertical drop out to compensate for a normal amount of chain stretch.
I post this not for the OP, who has decided a new frame is what he wants or needs, but for those readers who may not want to buy a new frame when the one they have may work just fine.
It seems at least one expert backs up my assertion:
