You’ll have to ask Ilford.
I can guess why, but I don’t want to take the flak for it :)

Ilford deserves a telling-off for that.
Perhaps Fuji might be persuaded to start producing Acros/Neopan in 220 format. Fuji is, at least when it comes to 220 colour films, the supplier with the widest range. I’d be happy to stock a box or two of those in the fridge.
I suppose we can’t count on Kodak.
