This is only a single data point, but I asked a designer colleague about 

"Perfect" grays (each RGB channel at the same value) with alpha are used 
a lot for backgrounds and shadows. A shorthand (however it is named) 
that allows not to repeat the value would help greatly, especially when 
tweaking the value.

Near-grays are used sometimes to give some "temperature" to the color, 
but not nearly as often as perfect grays (which are more neutral).
