In honestly never understood, why those parts are in the library anyway. I could not think of a reason to have them.
Actually I wanted to post this question since some time, so it is good you ask for opinions.
The only reason, is backwards compatibility of models in the wild...
But I think the colour hard coded parts are against the spirit of LDraw.

They were introduced when LEGO started printing part number in the instructions to try to prevent too many 'why isn't this part number in LDraw' questions. But the concept never really got much traction.
