I'd rather not have edge markings. Sometimes it's nice to do a alt process print "full bleed" style which requires the edges of the film in the print. Kodak's not too obtrusive with their 4x5, but none would be better.
I've settled on using two films in LF so I think I can handle two notch codes.
As you've suggested, better advertising would be fake film borders that say Ilford. They could probably prop up some freebie app store / itunes photo apps with name placement in film borders.
