It's not a myth... I guess they're just working towards making the thing... in the meanwhile you might wanna check out individual mods or other packs that are out already, and that, as far as I know, fix a whole range of things, and they are very well done stuff, I might add. Remember that GWX is good, but not the only one out there, you don't have to eat your fingernails waiting for the good stuff to come out, and it'll ease any probable impatience.
Oh, and, it has come to my attention that there's already a post for what you ask, sorry I can't point you to it, you'll just have to use the search.
Cheers
