Ok, seriously now. This might be a big issue in animation of some complex environment. We have not seen a full featured CGI environment with all sorts of artificial lights to enhance the atmosphere during an animation with lots of moving objects etc and all extremely sharp in 1080p. If corona continues doing so well and have all the popular features as hair and sss and so on(Btw I can imagine some furry stuff:D having shader with sharp reflections where it could be pretty problematic to avoid this issue) it will face situations like this.
Cause if some popular studio decides to try corona out doing some crazy shit, then avoiding direct and in reflection visibility of lightsources because of some aliasing or image filtering issue is out of question. You can't change the look of the scene in animation and tell the client it can't be done this way. As a studio you would have to choose another renderer and your product reputation goes down.
And this is something you know of. How much can appear once it goes commercial what you don't know about cause it has not been tested? You won't know how and suddenly there will be tons of people arguing with you why the product they bought is not working as expected. This is not a missing feature you can make your future client aware that it does not have. How would you explain to them that the white overkill:D is normal and how would you make customer aware of this. Would you state this behavior in features category?
Like it or not, once you get this commercial you will be sooner or later forced by some client to make this go away cause money plays. Why not do it before it is commercial to save time for future not known issues you will face? I don't know who do you want to aim your product at. As an individual you can live with this, not a really big problem. But as a studio with lots of bought licenses and some paid courses(big studios will gladly pay you to come there and teach their people how to use corona more effectively etc) you would be much less tolerant to stuff like this.
I wish you the best, don't think of this as a complaint, I love corona it has massive potential. I don't care, I haven't paid for corona now and I don't care how you do your stuff. But try statement "good luck fixing it" to someone who buys your product :D good luck with that man:D
