In my opinion you should avoid pointlessly merging with something unless you really don't have a choice. It's a pain in the ass to get it all together, and sometimes the other mods will require to make yours free/paid.
Also, I seriously doubt he has any features that you can't add on your own if you wanted to.

True, and even when that's added a Flashlight in FPSC would look horrible... You'd need dynamic shadows all over the level instead of Lightmaps, otherwise shadows from objects will never dissapear when you enlighten it. It'll just look silly. HOWEVER it IS a start.
It's not the world that turns against you, it's you that turns against the world.
