This makes sure that segments actually start at a keyframe,

AFAIK, this is not strictly needed, no?
Not technically, no, but given the way Chrome currently treats segments
that don't start with a keyframe it's probably desireable.
Also we'd currently have a small gap or overlap of frames between segments
in different tracks if we cut all segments at once, since streams without
b-frames would have a few frames belonging to the previous segment at the
start of the next segment (since their dts is higher than dts in streams
with b-frames).
