Because Source is incredibly basic in terms of shooting mechanics. I've barely seen any Source mods that incorporate advanced features such as tracers, ADS (on one hand, there are plenty of ADS Source mods, but there's very, very few that work well), advanced recoil, etc. For the most part, Source gunplay is literally just point and click, or, in Counter-Strike's case, crouch then point and click.
