A corollary was that clients should not depend on backing-store. It is quite possible that a paint application would perform better if there was some way to tell the server "if you can give me backing-store, you must guarantee never to take it away" and to query if it gave it to you. (Although a paint program that relied completely on screen contents would be a pretty fragile thing.) I don't know how many other such clients there are. If you feel strongly about such support, you are encouraged to write up a proposal, and work through your X Consortium representatives to get it adopted.
