The whole point of the spec is to make sure implementations are
compatible. Just discussing the "meat" and ignoring how things work out
in practice may backfire.
I think the example of SVG (a 'markup' language) having a codec
requirement that 3GPP then had to explicitly write-out is
instructive. The attempt there didn't work.
I would be curious for the reasons that 3GPP has taken the requirement
of vorbis out of the spec. Was that a decision based on technical
reasons and could you please explain what these technical reasons
were?
It happened before my time, but I rather suspect that the answer is
that 3GPP specifications have a set of required and recommended audio
codecs (AMR, AMR wideband, AAC, AMR WB+) and that there was neither
need nor desire to add to the terminal load a new codec. Someone
would need to come to 3GPP and convince the membership it's in their
commercial interests to require (and thus implement) a new audio
codec over and above the current required and recommended set, and I
doubt that anyone even tried.
