Requirement to fly Departure Procedures

The word on the street seems to be that with a departure clearance
from an uncontrolled airfield of "cleared on course" any ODP would not
need to be flown in VMC. . However, I'm not sure how the FAR quote
below, which also applies to Class C and B airspace, supports that.
Clearly, an ODP is established by the FAA. Anyone?

91.129 Operations in Class D airspace

(g) Departures. No person may operate an aircraft departing from an
airport except in compliance with the following:

(1) Each pilot must comply with any departure procedures established
for that airport by the FAA.

Perhaps this thread has been visited recently, and if so, I apologize.
