I think we should not specify and implement them. I acknowledge they they are useful, but like all -x and -y properties:
1) if we later decide we sometimes also want to declare things in terms of logical directions, we're stuck, as it isn't possible to simultaneously have a -start and -head. By keeping a single property, things like this stay possible:
transform-origin: start 13px head 10px;
2) users who want them can easily simulate then using varaibles:
* { transform-origin: var(x,0) var(y,0); }
#foo { var-x: 13px; var-y: 42px; }
