That's a mistake. Water will get under the silicon through the grout. It will peel sooner or later. Color caulk from tile stores would be the best choice I think. There's a product call Big Stretch. It will stretch 1/4" without breakage. I use it a few times on exterior wall and windows with great success. That's what's design to do but not in the shower. I am sure it will work because the movement is so little. Down side is that they only come in a few colors. Still I use grout all around, including the corners. Floating your showers will eliminate most joints from opening because it is one monolithic pour. With the clement boards, it will move along with the framing cause the joint to open. Float your walls and pans, plain and simple.
