Purpose of red trinkets (Oracle)

Can anyone tell me the right purpose of red trinkets? I think that its fine that you can reveal and disabling wards and reavealing traps... but disabling** traps**? Realy? It's like only anti teemo and shaco item. Nothing else. Because you can't see invisible champs, only their siluet, so you can't normaly attack them (only with nontarget spells or aoe. But when you can disable shrooms for 10s, it's like when you can deactivate other champs utlimates for 10s or more with 0 gold cost. Because it could not detonate by anything in team fights. (when 4 peoples have red trinkets it could be 40s with 60s cd in team fight) So i ask you again.. what is the point of red trinkets, when it's usless against invisible champs? If it's realy only for teemo and shaco, I would like to vote or ask riot to remove the function of disabling traps on red trinkets.

And yes I main Teemo and I know that there is too much haters. But when you can objectively look at this problem you must know that it's realy not fair. Please think about it.

PS: sorry for my english but i hope that you understand me
