And I just use this (or similar)

-- Set up basic event handler
local function SetEventHandler(addon, frame)
    if not frame then
        frame = CreateFrame("Frame")
        addon.eframe = frame
    end
    frame:SetScript("OnEvent", function(self, event, ...)
        if addon[event] then
            addon[event](addon, ...)
        end
    end)
end

But still. Would be nice to have it built in and standard.
