Xiph.Org's purpose revolves around the availability of open and
unencumbered media formats. Xiph.Org is generally happy to use, adopt,
promote anything which furthers that mission even things not invented

In order for a format to be useful a lot more is needed than just the
codec itself... Transport formats, tools, complementary codecs (e.g. a
video codec often needs a matching audio codec), so there can be a
role for Xiph.Org for that too.

I think to make Schroedinger lossless you want "rate-control=3".
