I completely agree. If Traits are something you really need, you're using the wrong language. If you need a screw driver, get a screw driver. Don't try to use the claw of a hammer. Developing with something like this will only increase the spaghetti factor. If you are a stickler for code re-use, my suggestion is to favor Composition over Inheritance.

It's also worth noting that PHP will most likely be adding Traits into the core language at some point. A patch has been available since 2008:

Hell, if you really need traits (you don't), apply the patch. Just don't mutilate your code base.
