As many will acknowledge, it is difficult to prove a negative!
The only observation I will make, as someone who has followed this carefully, is that we haven't seen reports posted here on this issue for a significant period of time.
And when it was at its worst, that was certainly not the case!
As I've said before (rather frequently) wrapper offset has always existed as a problem. Ilford had its own problems with it considerably before the relatively recent Kodak problems, and the relatively faint numbers on their backing paper were the result.
One of the contributing factors has always been unusual temperature and humidity during transport and storage. With the distribution network being so different now, I expect we will continue to see at least some isolated examples of this and related backing paper problems with all brands of 120 film.
Kodak Alaris believes that the problem has been resolved to the extent that properly stored and handled film won't exhibit the problem. They can't of course prevent it from happening to improperly stored and handled film. I would hazard a guess that current films may be more susceptible to improper storage and handling. One of the casualties of the recent "fix" is that the markings on backing paper are both fainter and less numerous - some older and unusual cameras can no longer be used with current Kodak 120 films.
FWIW, the only film I've had the problem with was TMY that came from one of the first batches identified as problematic. That film was replaced with more recent film by Kodak Alaris before I even used it.
In my case, I was using the problem film for testing, and I didn't care about the numbers. Even then, I didn't encounter the problem with all films from that batch.
I haven't seen the problem with more recent film. I should do more testing with the remains of my problem batch, to see if there is any change.
