I have no idea what you are talking about.
There's an insane amount of great out of production film out there that I've almost cried over for not being able to use it simply because it was not peforated. Think of kodak IR, tech pan, konica IR and even APX100 that's getting hard to find these days.
Leicas are cameras that I put through regular use. If I can use non-perforated film in it, it will then reveal itself as an even more capable tool.
What don't you understand "Rolls Royce" or "Diesel" ?.
