Unless by "fixed" they mean they are making it so you can repair the frames...
Nope, just confirmed with Luke that ship frame damage is disabled unless it is a derelict. Whether that means a ship sinking into the ground or just Unregistered I don't know, I would assume the former but couldn't say either way.
EDIT: Herb just confirmed it's only ships sinking into terrain which can be salvaged now, as intended.
