This is in fact one of the goals of the FLAC project.  From

"Free" means that the specification of the stream format is in the public
domain (the FLAC project reserves the right to set the FLAC specification
and certify compliance), and that **neither the FLAC format nor any of the
implemented encoding/decoding methods are covered by any patent**. It also
means that the source for libFLAC is available under the LGPL and the
sources for flac and the plugins are available under the GPL.

As I understand it, the current Ogg/FLAC implementation simply wraps the Ogg
bitstream format around a normal FLAC stream, thus not utilizing the
features of Ogg, and duplicating various bookkeeping data.  If the Ogg folks
were to spec out a FLAC-based codec for Ogg, it would likely look different
from the current implementation.
