Because ambient_light affects all ambient in the scene. Adjusting the 
default texture instead lets me override it for specific objects that 
need it, like a glowing LED, a neon light, or a computer or TV screen.

I've been doing something similar with diffuse...setting the diffuse 
value in defaults and only adjusting pigment color in the textures. I 
can then adjust the diffuse value in defaults to control the overall 
brightness of the scene...this is pretty helpful with radiosity.
