On my Mariner I had the cleats were kind of recessed and those on the .5 stick straight up in the air. You can set if up any way you want. I could see those hooking on other kayaks perimeter lines in a rescue. There's nothing written in stone you have to rig a kayak the way the manufacturer did.
Basically the rigging is for your use, if you don't see a need get rid of them or try something else.
I got used to having the recessed cleats on the Mariner so that when I outfitted other kayaks I ended up installing 1" webbing loops or a ss D ring on the foredeck for attaching a painter or quick tow line.
