No paper certainly makes it easier but I suspect that Ilford add the notches to a stack of film rather than individually.
If Ilford were to do it, it's just an extra stage which would translate to extra cost which would have to be paid for by us.
Firstly, It was me who took this very 'off topic' so I apologise.
In finishing sheet film, you cut the lengths off the the parent roll, so for 10 x 8 sheet you cut an 8" block x the parent roll length ( say 1,500 linear metres ), and other widths off the same parent rolls at the same time obviously, that block is then 'chopped' in a separate ( automated ) process into the 10" dimension ( and at the same time the notches are put in ). I would imagine ( but do not know for sure ) the edge signing would be done when its in the 8" x 1,500m state as an optical in line process from the big slitter. We have no such in line optical exposing device, we have never had one for sheet, nor would we believe we have any real customer value in adding one. So obviously if we did it, which we could, the cost would need to be passed on in a higher product cost...do not want to do that, do not think the customer needs it either.

We have no such
I enjoyed the off topic talk and you have nothing to apologize for.
As far as I'm concerned the moment you posted saying it wouldn't happen, was the moment the issue was closed and the fun of posting silly off topic comments was perfectly fine and welcome.
BUT since the consensus is it is not a good idea....
I will say that I do occasionally see portraits that Fred Lum does for the Globe and Mail, he often uses a sheet of film with the makers name at the edge of the image to get a bit more eye capture effect. (sometimes sheet film and other times 120) so I can see where having the branding might be useful to some, and would remind folks that Illford is around and does make film. OTOH I can also see folks objecting to the "free Advertising effect"
One thing I would not want would be the branding that was on the Illford 35mm Cine film. That had both footage numbers and "Illford Safety Film" printed every foot with the writing reading correctly from the EMULSION side. (It did make sense for a film editor to have the numbers reading right from that side., but misusing it for stills the writing is backwards on the proof sheets. I still have a few feet of Pan-F marked that way in my fridge from a close out 200ft roll I bought year and years ago)
I am surprised that no one has mentioned that the notch codes can be "read" in total darkness. This was probably their original intent. They can also be used, again in total darkness, to determine which side of the film is the emulsion side. So they are really more useful than edge markings.
This is not a practical thread way off topic…
But in a similar vein photogs who had six or more identical blad backs would nail file an additional notch in each so they could tell which back a film with eg a light leak or bad frame space came from... don't everyone do that with dark slides/film holders?
