why aren't we allowed to have the pink ward trinket?

please explain. actually someone from riot explain this one to me, i don't get it. historically, contextually, at the time, sure i can understand removing it because vision as a whole was busted, but it wasn't the trinket itself making vision broken, it was the availability of regular wards thanks to sightstone and junglers building the item which was unintended.

it was such a fantastic tactical trinket i can't understand why it stays gone. especially for the late game where you don't have the space for vision wards in inventory. i mean i still bothered to watch competitive at the time and the item functioned as intended, one person on a team would get it and there would be a pink ward in hand that the team could play around. but even then it was only picked up maybe once by either side in a bo3, almost never seen in the bo1's, occasional use in soloq. the item had a real function to serve, and still has one to serve in the current game but we just aren't ever getting it back because? has the live design team forgotten the item existed? :/ you can rectify so many woes about the current game state by bringing it back, even if people get nifty with the trinket swapping. am i missing something here? it's not like it only serves 2-3 champions on the roster like other items
