Yea it's a very uncommon thing, but I am working with J2ME apps for mobile 
phones. Part of making an app smaller in filesize or take less memory on a 
mobile device is to optimize images and explore different image types. Some 
apps we've come across have code that specifically needs something like an 
image to be e.g. "2-bit grayscale" in order for something to happen (or another 
example having to do with palettes... that it requires colour "3,3,3" to be in 
position 4 of the palette).

I would appreciate sub-8bit support in GIMP... it would definately be a reason 
for me to use the program more often.

Not many people would need this kind of stuff tho =).

Nobody have asked, that I recall, saving in indexed formats with 2 and 
4 bit.

This is not hard to do code in the GIMP PNG and maybe some other 
format. (bmp, or tiff)

Do you need this feature?
