I'd like to reinstate the ability have the lisp side be able to evaluate arbitrary forms from presentation menus. If there is a security issue for some I think it would be better handled by having a switch to disable evaluation of these forms, with the default being that they are evaluated.
And to be honest, I can't see how disabling presentation menus from evaluating forms in emacs enhances security when one is already sitting in a repl talking to the lisp.
Also, the recent move of the inspect, describe, and copy to input functions to the emacs side removes the ability to specialize the method on the lisp side to not offer those choices. If there is good reason to move them over, which I'm not convinced of, then it would be better to still return a value, say a keyword, to represent these actions so that they can be overidden.
