It's more about looking over the source code of the KeepassX app and just that (not all applications you use, of course we have to trust some of them), the code changes are (when there are changes) ~10 lines a month, not a huge amount to check.
So if there are rules to improve the privacy of users, I would worry about making it look to complex or extreme. I suspect rather than picking some parts that work for them they will go "ok this i can do, this I can do, and .. wait compile it myself and read the source?! - ok, I'll stick to post it notes".
