It is a ridiculous exercise in red tape. I have never sent one in.

You should be aware that your actions(or lack thereof), mean that you do not conform to the operating limitations that are part of your airworthiness certificate.
It takes me about 45 minutes to do letters for all 3 of my Ex- exhibition/air racing ships.
Take the little time and do the letter and avoid the risk of an unairworthy glider.
FWIW, when I do condition inspections, if there is no program letter, the glider does not pass the inspection. Yep, I'm a prick, but the guy signing off is representing that everything is correct, including required documents on board.
