Since murkmire the event EVENT_ACTION_SLOT_ABILITY_SLOTTED does not fire anymore. It seems to have been replaced by EVENT_SKILL_RESPEC_RESULT or EVENT_ACTION_SLOTS_ALL_HOTBARS_UPDATED, but i cannot find the first one in the API updates.
And? I am neither Ayantir, nor do I use the wiki. Since it is a wiki, you are free to update it yourself. I believe Ayantir left instructions somewhere.
