See page 20 "Freeze bitstream format" with a check mark to its side
Page 3 too "WGLC (Working Group Last Call) last minor bitstream changes"
There are probably more details about this in the video.

I probably misinterpreted your "Sticking to celt051..". Of course it's the
best alternative compatibility wise, but the reason for this thread is that
Debian does not want it.

As long as we don't drop celt051 support, that Opus can be disabled (it can
be be disabled by default), that our position about
compatibility/interoperability is clear, having support for it would be a
good thing, especially since it would mean a good SPICE in Debian. Maybe
I'm putting too much trust on the Opus people not making regular breaks to
the Opus bitstream format, but I think it's a chance we should take.

Experimental and unstable as in "being standardized by IETF"? Opus is not
final yet, but a this point I hope it's out of the experimental zone and is
stable enough.

And this would magically trigger a celt 0.5.1 update from the spice team? I
assume you were talking about making new celt .tar.gz available.
