But you forget that the default flag applies to all kinds of track, not 
just subs. The default flag is to tell "if you don't know what track to 
use in the list, use this one". It doesn't say anything else.

The forced flag would say "regardless of the playback option, this track 
has to be used". At least that how it works on DVDs. But I would prefer 
it a nicer way, ie having multiple forced track, one for each language 
supported and a default one if the language is not found.
