I disagree. it's all "maybe sometime in the future", afaik we don't do
any checking now and it doesn't look like we'll start anytime soon.
because of this, almost nobody cares if the ident string gets writting
correctly. e.g. the mp3 muxer writes it twice, once normally and once as
a TXXX frame. Justin noticed this a few months ago, yet nobody cared
enough to fix it.

with my patch it'd break when all other metadata writing breaks. IMO
people care more about writing metadata correctly, so it would get
noticed/fixed much faster.
