Disagree, the 780s have space 3 maybe 4 bags in the closet, with the most frustrating sized bins to work with.

A lot of us keep the closet(s) door closed during boarding, at least till we know J class bags are good. Otherwise random people seated in Y (who's bags will fit in the bins) just put bags in the closet. There's a number of times I've had people ask can we stow bag in closet, I say sure, only to find the closet full of random, poorly placed bags, that means a bunch of time faffing around trying to get the closet re-arranged.
