Thats certainly an option, but its a trail and error thing that some users 
would have more luck with than others, and it has the disadvantage of not 
being previewed in Photoshop, only applying blindly on output. Then there are 
the issues of remembering to use it or not use it, and having to have 
different transfer curves for each paper, which is not much different than 
using profiles, admittedly, except that a profile based workflow is pretty 
common and obvious, and not too inconvenient, while a tranfer curve is an 
unusual item you need to remember seperately. The final arguement is that you 
really need to have a good profile for the printer for color images anyhow, 
and once you have it, applying it in the same manner to your grayscale images 
is easier than building and remembering to use a transfer curve.
