They represent analog, color specific density scales for each color channel. 
Which can be useful for certain older functions utilizing density values for 
things like linearization.

They mean something. Its just not something directly translatable to color 
values; its for other purposes.

Yes, pretty much. An analog densitometer only offers density values, in one 
or another density scale. It does not offer color data, and (a question I 
receive about once a week) you can't use the data from it to build ICC profiles, or 
do other color related things.
