Do temporary weapon enchantments still exist?

[Choonstertwo]

A long time ago (back in Cataclysm), I wrote a DataBroker plugin that tracked Rogue poisons and Shaman weapon imbues using GetWeaponEnchantInfo.

In the process of updating it for 6.0, I've struggled to find a temporary weapon enchantment that still exists. Shaman imbues have been removed and Rogue poisons have been converted to regular self-buffs.

Does anyone know of a temporary weapon enchant that's still around or is my AddOn completely useless now?
