Up for debate.  An automatic approach brings hesitation to me, because I don’t want it to be the difference between:

protocol P {
  var x : Int { get }


protocol P {
  var x : Int 

Did I want a PwS there, or did I just forget {get/set}?

Marking the protocol with an attribute or declmodifier would solve that.
