It has been talked since ages, but since Cycles is an Unbiased render engine path tracing, then it won't have such a feature. Also this is not a bug so you shouldn't report it here feature requests, but here. And caustics in Cycles are calculated yes, but you need a lot of samples to get them to show. I would suggest you to use the Denoisier to remove the fireflies if you are using them.

LuxRender (also called LuxCore) is the best open source render engine for accurate caustics and dispersions, here, don't worry if it is still Beta for Blender 2.8, it's pretty stable.
V-Ray here and Corona here. Have fun.
