i would like to see something like caustic blur

octane render

Caustics should only be determined by material, geometry, and light source. Introducing a blur effect would alter the final result in an inaccurate way. Octane uses the trick to speed up caustic conversion at the cost of rendered accuracy. For this reason, it's my opinion that this effect would not fit with Maxwell's strategy.

with a slider you can choose what kind of accuracy you want.
