Will there be enough Trap Detection on Howling Abyss in Patch 4.12?

In the current patch (4.11), Howling Abyss has two items with the Trap Detection passive - The LIghtbringer and Hextech Sweeper - as well as the temporary Oracle's Extract which reveals all stealth. However, Patch 4.12 is reworking The Lightbringer and it will no longer have the Trap Detection passive or the reveal active. Trap Detection is being added to Spirit of the Ancient Golem and the reworked Grez's Spectral Lantern, but those are simultaneously being removed from Howling Abyss. And for some reason, Howling Abyss uses the Summoner's Rift version of Twin Shadows instead of the Crystal Scar/Twisted Treeline versions which have Trap Detection.

While there are not many champions that use stealth traps, the few that do (namely Teemo) can be quite oppressive without sufficient vision options due to the constricted space of the map. And now, the only choices will be Hextech Sweeper for some tanks and bruisers, or constantly spending on Oracle's Extracts for other classes. Riot, please consider at least switching Twin Shadows to be the trap-detecting version and getting Trap Detection back onto some kind of AD item.
