Why is infusion of light not in the updated cooldown manager?

No, I cannot hear the proc sound

Separate from the many other shiny lights and effects on screen? No. It is not reliable or sustainable when I need to very quickly ascertain whether or not I have Infusion.

I can track many buffs through the cooldown manager. What I am asking for is for a single buff to be included that is not. It is an intended part of their current approach for me to be able to track buffs like this.
