I think that's reasonable, but is syntactic sugar really going to help you modify a path when the vector points will look more like this in reality:

  (path (M 368.296, 1.514) (c -0.908, 0 -1.818, 0.011 -2.716, 0.021) 
  (c 0.053, 0, 0.106, 0, 0.159,0) (c 147.196, 0.836, 265.306, 94.672, 267.029, 183.784)
  (c 0, 0.581, 0.065, 35.087, 0.065, 35.087) (h 49.415)
  (v -33.471) (h 37.094) (v -31.376)
  (C 719.342, 77.099, 575.826, 1.514, 368.296, 1.514)
  (z))
