First of all, I love this feature. But I’ve got a small question.
Is it possible to turn off denoising on certain objects? I do aereal perspectives and the denoiser tends to smoothen my asphalt roads in too silk 
I know I can save a normal render and a denoised one and use a mask. But I was just curious if there is a more automated way. (specially when batchrendering)
Currently not. I doubt it will be developed, as the VFB is already filled to the brim with features. You can obviously make a proper feature request and the devs will consider it.
I recommend a Photoshop Action script / droplet. I have done tons of fun programming work, which I cheated through with calling Action scripts in Photoshop 
Although it is an extra step, it might automate the “anti denoising”.
Yeah well, it aint that big of a problem. So not really a need for a real feature request .
