Maybe worth mentioning that the zero plugin is more efficient than
'ones byte=0'.

Otherwise looks correct, and while it probably won't be the most
frequently used plugin, I can see its utility as being more efficient
than the corresponding use of data plugin in read-only mode with a
disk pre-initialized to a repetition of a given byte.
