ok, let’s assume for now you are right, it doesn’t matter. If you want you can write on this documentation page http://codex.ww.wp.xz.cn/Function_Reference/wp_deregister_script explaining of much they are wrong and deceiving.
Do you agree that when you include your script you should specify that it depends on jQuery? Can we just agree on that so I don’t have to fork your plugin?
Because I want a different version of jQuery, what’s wrong with that?
And, if you assume you should not, why do you bother to register it on your plugin?
