The only reason IFR flight plans are required in the first place Is for search and rescue.  The controllers could care less about a flight plan.  When a controller "may" ask u for the rest of the flight plan it's not for him unless its a long drawn out route,and your option as a pilot to provide it.  For IFR pop up through a cloud layer with intent to go VFR is an approved procedure.  You are on an IFR clearance and if you want to talk semantics then technically you are on an IFR flight plan.  I was an ATC for 24 years.  Not something I just think I know.   The only thing a controller is interested in is what type plane you are in and the route you want to go.  I once asked a good ol boy his type aircraft and equipment.   His response was......well, thanks for asking.   I have a 1977 Cessna 172 with the Nav II pack.  I asked his destination and he or proceeded to tell me he was going to his sister in laws wedding in eastern Nevada.   Imagine a long slow Texan drawl.   All I wanted was.  Cessna 172 slant Alpha.   I asked his cruising altitude and he said.  "Well, I'm just going to go over these mountains up ahead if I can clear them".  

Not sure what ever happened to mister pilot , but rumor has it he was killed in a new pickup truck.  Last words were.  "Hey bubba, watch this"......

Don,

   Care to expound on your one word statement?  If this is wrong, someone needs to tell the controllers who have approved it each time I've requested it.

Possibly IFR to VFR on top, then cancel. I've done that a couple of times to take off from coastal airports with a marine layer that only extended a few miles inland. Don't need a flight plan to do that.
