I don't think so. As we go through this thread, and see people talking about flying out of Class B and "entry into the system" I am wondering whether we are talking about apples an oranges. VFR traffic, except for Class C and Class B is not entering any "system".
IFR
Primarily Clearance Delivery is a control tower position for the purpose of relaying IFR clearances to pilots prior to departure. At some Class E and G airports (usually one near Class B or C), there is a remote to a nearby airports' CD position to avoid the problems associated with void time clearances and busy airspace.
VFR
At airports within Class B airspace, CD provide VFR class B clearances to departing VFR aircraft. At most Class C airports, they also provide VFR departure instructions (I'm avoiding the use of the word "clearance" in airspace that has a communication rather than a clearance requirement).
In Class D, some towers, especially those near Class B or C airspace, use their CD position to provide clearances for aircraft that will be entering the overhanging Class C or D. At some it's "required" and when this is the case, ATIS will usually have an instruction to that effect.
Some Class D CDs and Class E CD-outlets can also be used to obtain advance clearances for VFR traffic what will be entering the nearby Class B or C. And some will provide VFR squawk codes for departing VFR that want flight following (although you can get these from Ground as well). But not all. And nothing in this paragraph is.
But, calling a Clearance Delivery channel at Class D or an CD-RCO at a Class E or G airport for the purpose of departing that airport for a VFR flight into Class E or G airspace just because there happens to be a CD frequency listed? Sorry. I just don't see the point, have never done it, have never been asked to do it when checking out with an instruction at a new-to-me airport, and can't imagine why I would teach it. I can just picture the response of the Tower at Centennial (APA) a Class D that is in the top 20-25 busiest airports in the country and 2nd only to Van Nuys as a GA-only Class D if every VFR flight called CD. Tower would be visiting the flight schools on the airport and saying, What the heck are you teaching.
