-hls_wrap <num> does achieve this more or less, but the option has been
proposed for two reasons:
(1) Simplify compliance with HLS Internet-Draft
6.2.2., Live Playlists:
When the server removes a Media Segment URI from the Playlist, the
corresponding Media Segment MUST remain available to clients for a
period of time equal to the duration of the segment plus the duration
of the longest Playlist file distributed by the server containing
that segment. Removing a Media Segment earlier than that can
interrupt in-progress playback.
The playlist length/duration can change without computation and
modification to the -hls_wrap <num> argument.
(2) Although not required in the HLS Internet-Draft, it can be useful to
have the sequence number in the segment URI for tracking when logging and
making modifications to playlists.
Thank you for your consideration.
