And by your logic every program that needs to write ogg files should do
all the encoding manually by itself.  This is most certainly not the
case for brutally obvious reasons.. these reasons apply to our situation
just as well (if on a lesser scale).  If you want to write an ogg file,
you use the ogg library.

It's not like the file format isn't going to be defined at all.. of
course it's going to be "defined at the file data level".  That doesn't
mean every single application should be mucking with that file
manually.  That would be stupid and counterproductive.

I still have no idea why the heck you actively want to load way more
work on yourself for no benefit whatsoever.  Why deal with version
numbers, and compatibility issues, and manual parsing, and blah blah? 
Very many problems, very few (if any) benefits.
