Nope. But if you crop to a rectangle (as I do maybe 1/3 to 1/2 of my square images shot with my Yashicamat) you end up with 6x4.5 or so crop, depending on aspect ratio of the cropped rectangle of course. 6x7 is nearly twice as big. And you don't get 7x7 Fujiroids as discussed above.
BUT - I could walk around and shoot handheld with a Hassleblad about as easily as with my M645 Super. Not so an RB or RZ. Oh yes, you CAN use them handheld, but I wouldn't want to carry one around all day, or even a couple of hours.
I am not in love with the 1:1.5 ratio and I tend not to need to crop in any format because I compose for the format. I agree with you in the last sentence. The RB and RZ are more than a handful and I do not like handling them.
