The skeleton I-D is part of the Annodex specificatin at this point in
time: http://annodex.net/TR/draft-pfeiffer-annodex-02.txt
We should probably split that out, but it won't we much work.

You would be amazed about how many tools already support skeleton. VLC
has support, liboggplay has support and thus the firefox extensions,
xine has support, and Tahseen implemented support for the encoding
tools, though I am not sure whether those have been merged into trunk
and been released. You are right though that there is a whole pile of
work still to be done. But if we want to move forward with the new
formats in a sensible way, a "SHOULD" is the right way. It's not a
"MUST", so it lets us do the transition gradually.
