I'm not sure I understand your distinction. As I understand it, only the first
packet that contains the first byte of the start code for a keyframe is
considered an access point - not 'every packet belonging to a keyframe'

I don't know what the spec says, but I'd be surprised if it says anything other
than you put one entry per half second or so, pointing at the first packet that
contains a piece of the first keyframe for that half second, and GOPs should be
structured such that every half second of video is self contained, like it was
on DVD.
