Indeed, I agree. I sometimes do that, too, when I want to
emphasize the idea of "applying tools one after the other".

But most often I just use traditional "function composition"
notation. That reminds us of the connection with mathematical
functions. It also raises less eyebrows when other people read
my code - some people immediately panic when they see an
import from Control.Category or Control.Arrow. :)
