  where is that discussion? could it be linked here? (sorry, I have no recall of it so i am not sure even what to search for)
  
  personally, I would find this behavior way more intuitive, for the menu button, i expect it to open the menu on click, no matter what i configured for double click which is a completely different action from the user POV (also given that Windows has this behavior since windows95 it's something pretty entrenched in the expected behavior for  that menu button)
  it's just.. a bit complicated to implement, but that's an implementation detail, not to influence the ui... unless it can't really be avoided.
  Long press on desktop is generally bad, i know we have it for some toolbuttonsand for plasmoid handles, but none of them are optimal, toolbuttons should definitely be solved, for plasmoids a bit more difficult, but should be improved as well
  
  looking at the code, it seems to make sense to have a delay that corresponds to the double click interval, that may make the popup feel not super immediate(so the timer stuff is important is enabled only when the double click to close is enabled), but better than the unpredictable and undiscoverable long press.
