Speculation (i.e., I did not look at the code): Z means 2^70, Y means 2^80, so they are both too big for unsigned 64bit integers. Thus they may be too big for du? > Why are those suffixes listed as valid under the program 'usage' > and manpage, when they are automatically disallowed? Perhaps they are automatically used with sufficiently sized integer types, i.e., this may be future proofing? You could look at the code to get a deeper insight.

They are valid if your computer has wide-enough integers. As far as I know no platform supports Y and only one or two supports Z, but the documentation is future-proofing. Conversely, if you're running on a really small computer that doesn't even support 64-bit integers, even 'T' is too wide. I doubt whether it's worth complicating the manual for this minor detail, as the current diagnostic "'Y" too large" is accurate as far as it goes.
