I’ve been experimenting with different settings across highlight reconstruction & filmic, turning HL-recon. off included. The worst case scenario is using Filmic RGB with chrominance preservation + modern chromatic adaptation when lighting conditions are far from D65 illuminate.
Unfortunately that is the case when shooting indoors: artificiall light around 2700 K, so leaving white balance at “Camera reference” is so huge difference, that close to overexposured areas become ugly; applying CAT on top of it makes things crazy, and treating all of it with Filmic chromatic preservation makes one huge “ka-boom” 
Of course I am aware that it can be my lack of understanding (despite countless hours of investigation), but for the time being, I find the mixture of the base curve and classic white balancing the most robust and treating highlights and overexposure exceptionally well 
However, I trust Aurélien and his knowledge, I believe scene-referred workflow is the future and I am able to use those tools like Filmic e.g. in landscape photos, but it certainly doesn’t work for me with typical indoor shooting.
I push myself to go full scale on scene-referred, but further training is needed. Maybe future versions of CAT and Filmic can solve my problem.
Thanks for the tip anyway
