Actually, GM can be very useful for a number of things, the first of
which is transportability. It does address a semi-finite set of timbres
but for pieces that use these, it is quite simply a blessing not to have
to remap all programs/patches to fit a particular sound-generating
device. Csound is a sound-generating device, a highly programmable one.
Adding GM compatibility to it in no way alters its generality.
