Not so. An index with b_max=0 would need to specify the position of every
keyframe. If a keyframe is dropped, then the index must have b_max at
least the distance between the page containing the dropped keyframe and
the page containing the preceding keyframe.

Fair enough. I don't know much about how Xiph standards become
"official", but I'm not intending to hold up the process. If I care
enough I can always propose it as the next version.
