Octane 2019 vs 2020 emission Denoiser Tweet

[Goldfinchworks]

Hello everyone!
I noticed issue in denoiser behaviour in 2020 Octane versions. Denoiser ignores emissive objects and leaves them with jagged edges (in this scene i used falloff for emission, but same scenario happens with ordinary emission).
I suppose this issue somehow connected to adaptive sampling. In 2019 version Octane sees emissions as it used to, but in 2020 it just ignoring them, just like it ignoring the light source.
My question - is this a bug or it is just intendent feature?
Thanks!

Joining Goldfinchworks with his question, but not only with Denoiser feature
Earlier builds (V3-V4) gave a cleaner emission look, especially in defocused zone. Not much cleaner, but cleaner.
I attached an image with defocused lights, that has ugly pixelization look. And denoiser just ignore that areas, more-samples-way gives almost nothing.

P.S.: can't remember exact, but in V2 or V3 there was a lifehack that worked brilliant for dark scenes - no alpha, set samples to 1, but turn on Post (glow), and use in compositing just Post pass with Add/Screen methods.
Beastly fast very clean emission look!
(don't know why but in last versions Post pass calculated long with mid-noisy result)

What can we do now to get clean result? ((((
