Keith,

If it merely used the green channel, it would be losing information.
Typically, scanners that scan B&W in RGB, of which is %99.999999 of them,
they scan in RGB and use some precanned "mix".  This mix is based on someone
else's opinion on what is best...so most people simply do a full RGB scan,
and convert in PS using their own mix.
