What are the Cons Of Tripping Knox, Especially On S5

Hello,

First Of all, Sorry moderators, if this post is repeated, Kindly lead me to the post which exactly answers my questions,

I had been into the rooting, custom roms stuff from a long time though, but the phones I used to have before didn't have any special sensors, I bought a T mobile S5 which is already on 5.1.1, so there isn't any way to root without tripping Knox 0x1,
I actually wanna know that what harm it may give to the features, will I loose the finger Print lock, or the gestures?
Really Curious to get the answers so that I can decide whether to go for the root or not.

Thanks In advance :)
