We probably can assume that it is at a depth that would preclude access by even technical divers breathing mixed gases. Otherwise, it would have been found and looted earlier.

The wreck could be pretty safe if left alone, as any salvage operation likely would rely on surface vessels carrying submarines capable of reaching the depth of the wreck, and such an effort would be pretty easily detected. I don't know how much of a marine museum it would make if no one is able to access it, but I have no problem leaving war-time wrecks undisturbed as memorials to the deceased crew members.
