It's a good reminder CF.
I was caught out a couple of years ago when I diverted to Maastricht Beek (EHBK) on an IFR flight to Spa (EBSP). I expected Beek to close the FPL -- presumably by sending an arrival message -- but they didn't and was intrigued to find my departure airfield calling on my mobile a couple of hours later after Brussels AIS chased them. No major harm done, but the lesson is that it never hurts to call your intended destination directly.
