Does your workaround work for all supported backends, and with alpha 
less than 1?  If so, what is it?

Except that in typical mpl usage, None means use a default.
For colors, 'none' (a string) means no color, so a line should not be 
drawn.  Elsewhere in mpl, lw=0 also means "don't draw it at all", so it 
seems right to me that it should do the same for 3-D.
