I did a google search and it seems it's mostly about it not tasting good and having a bad texture, which makes sense, cabbage doesn't reheat well either. I did find some recipes for canning colcannon which includes cabbage. I just did a search for canning potatoes and cabbage, maybe that will help you.
I think it's likely that people don't can cabbage often because it keeps very well in other ways.
