Roll-up captions are, as far as I can tell, just one cue, that happens to have
internal state (much like a karaoke cue, actually).

The problem with using the current cue concept for live cues is that you don't
know when the cue will end (which it may well do before the end of the stream,
e.g. if the live stream has prerecorded segments spliced in, e.g. ads), yet our
cue format puts the end time before the cue text. Hence the desire for a
different format for live cues.

Streaming definitely doesn't preclude seeking. Live cues definitely don't
preclude streaming. The question of what to do with edited cues when seeking
back seems quite valid to me.
