Such a drastic change cannot be done for POV-Ray 3.x but it could be 
considered for a future version. Usually, after 1 level of texture_map 
nesting, my brain starts melting down when defining textures in POV-Ray, 
while I don't have this problem when using separate channels in other 
softwares ;-)
Really, having all surface properties independent and controllable by a 
combination of a pattern + specific modifiers is extremely efficient when 
creating textures and gives a lot of flexibility.
