That is not a completely accurate characterisation.
We have provided some assistance to this format by showing how to wrap this up using the components that Apple supports for extending format support in the system.
Specifically, at the source forge rep, there is an AudioCodec (encoder and decoder) and an AudioFile component (that will read/write FLAC files).
We don't distribute these in the OS, but for the desktop we provide a means by which you can support these formats in your applications through the existing API (such as AudioConverter/AudioFile)
