I read all the comments and i still don't get why is not possible to implement a bypass feature, just enable the button when it is applicable. For example, i always press backspace to see the results without a levels node and them do a ctrl+z after to see the results with that levels node again. I do this "Select-BackSpace-CTRLZ all the time, and it is practical in many situations and it would be way easier if there is a button that does just that. Just don't call it "Bypass", call it "Disable and relink" or "Go Around" or whatever makes sense. Why a "delete and relink" command is possible but a "disable and relink" is not? As i said, enable the option when the software detect it won't break the graph. If the node is a 3 input and 5 output and the softwarwe does not know what to do with the connections, simply do not enable the option for that node, but i don't see why can't i bypass a levels node that is connected to a slope blur.
