That's not quite right. Originally we just had -khtml- for CSS extensions, and then we used -apple- for features that we were Apple-specific, i.e., that we knew nobody else would care about. Those features include Dashboard regions and Safari RSS line clamping). Eventually we just decided to merge both into a common prefix, but we wanted to keep the old property names working for compatibility. It was convenient to just map both to -webkit- rather than actually checking the specific property names and only supporting either -khtml- or -apple-.
My recommendation would be as follows:
(1) Drop support for -khtml- completely.
(2) Continue to support -apple- for -apple-dashboard-region and -apple-line-clamp only.
