I don't know anything about this particular decision, but it is somewhat
related to a discussion I started here a few weeks ago regarding add-ons
for and additional libraries for octave. The problem with FC's octave is
that there are some optional fast libraries such as ATLAS and FFTW3 that
are not included in FC. Some FC users on the octave mailing lists
actually recommended against using FC version and building your own. I
had suggested that we consider moving octave out of core so it can be
linked to some of these other libraries. I think it is necessary to add
the new libraries to core or move it all to extras to make octave most
useful. It appears octave is also missing from core, so this may in fact
be what has happened.
