glGenQueries only reserves names; a name becomes a query object when it is first used with BeginQuery or QueryCounter (GL 4.6 core 4.2.1). MobileGL created the live object eagerly at glGenQueries time and glIsQuery reported every reserved name as an object, with a comment noting the shortcut. The registry already distinguished the two states -- a target of 0 means the name has never been used -- so glIsQuery now consults it, and a name that came from glCreateQueries carries a flag saying it is an object regardless. glCreateQueries itself was a stub. It creates the objects outright with their target already fixed, which is the whole point of the DSA form: there is no binding step to infer the target from later.
