You guys are probably off on some IRC channel somewhere discussing these
things, but... why 64 bits for the CODEC identifier? 32 ("PCM ")
should
be fine?

Why store N-bit in the most significant bits and not least? Doesn't that
mean an application would likely need to shift everything down again?

Pedantic: the sentence "Format IDs below 0x80000000 are reserved for use
by Xiph and all the ones above are allowed for application-specific
formats" leaves the use of 0x80000000 itself unspecified.
