Fringe on mobile render?


I have read that the Fringe/Chromatic Aberration effect is not supported on the mobile postproc pipeline. Is there any particular reason for this? I would be really happy to sacrifice some performance on the iOS devices while running through Metal to get the aberration working. If there is no hacky way to enable it, I am thinking of writing my own aberration shader and forcing it into the pipeline through code. Is this a really bad idea?

UPD: Upgrading to 4.12.5 and enabling tonemapper added fringe!
