It is getting set automatically in lisp-interaction-mode and in the Lisp debugger. The manual doesn't say anywhere that this is being done. I would prefer that it doesn't get set automatically, given that it has a tricky behavior. In the light of my previous bug report #8548 that the debugger can't exit recursive editing levels, making any kind of typing mistake while working with the debugger puts it in a recursive editing level where it gets stuck. http://debbugs.gnu.org/cgi/bugreport.cgi?bug=8548 If you don't want to change the lisp-interaction-mode and the debugger-mode, can you at least document it in the manual that the variable gets set in these modes so that the users can unset it in the mode-hooks? I have suffered for several years needlessly. (By the way, edebug doesn't seem to set the variable.)
