    Is it true that a StoreColors request on a GrayScale colormap must always
    send values for each of red, green, blue (i.e.  the same value, three
    times)?

Yes.

    However, it seems unnecessarily inefficient.

Hardly.  The protocol request is going to have the bytes for all of those
values anyway, the only real "overhead" is you setting them up.  Not a
very big deal.  If you're suggesting that there should have been a separate
protocol request for this special case, to send fewer bytes, I would argue it
isn't worth it.
