Most definitely not!!
Subtitle has a 'codec' just like audio and video, and has a specific
interpretation that should be supported by all players. Metadata is
just the same useless crap that can be put in info packets, tagged
key/value pairs, except that it's muxed in the file rather than in a
global header so it can represent info that changes (such as new song
title on a radio).

A wrapper layer that does the necessary buffering to ensure that
packets are submitted in proper order would be nice. The muxer itself
should die with fatal error (or reject the packet with error code?) if
a packet is sent with a timestamp in the past and pts==dts.
