Irradiance Map and reflective GI caustics

[Art48]

I just noticed in the new VRay 3.3 that the log says IR doesn't support reflective GI caustics.
I couldn't find anything in the documentation about it.

I was kinda shocked by this, I never knew it doesn't support it and we light our shots usually with reflective caustics in mind and I was wondering if there is a plan to implement it in the future or if this is a technical limitation that can't be solved with the IRM.
