I don't think so...

The fact that they can't store any display duration just prevent
them from storing plain text subtitles. At least I think so.
Another possibility would be to not support any kind of plain text
subtitles at all in ffmpeg. Demuxers could convert them to SRT,
which is basically plain text + timing information. But I'm still
not sure if I really like this solution.
