Glad I could help! To answer your other question, the node setup you have is definitely not the best way to save render passes (although I've been forced to do the same thing in order to work with legacy pipelines). Look into the Multilayer OpenEXR format. Choosing this option in your main output settings will cause all enabled render passes to automatically save to a single .EXR file without any node work or technically incorrect color transforms.

Ivo van der Lans (Ivo) added a comment to T53790: Design Doc: Sample based compositor.

With recent advances in Monte-Carlo ray tracing (and specifically the VCM type of renderers), I suggest to use a bi-directional path tracer (with? MIS) instead of the currently proposed forward path tracer. Or at the very least, implement a reverse path tracer where rays start at the source images (the emitter) where important samples (highlights) are easily identified before tracing commences (also enabling Metropolis tracing). This is all the more efficient since users will typically blur the input a lot more than they will want to sharpen the output.

I think we can merge this into master quickly, I don't really have any issues with the implementation as it is.
It can be committed disabled by default, and then we can commit precompiled libraries, set up the buildbot and enable it by default soon after.
I would like to unify this with our existing denoiser (or other future denoisers) at some point, preferably before the 2.81. The current Cycles denoiser could be made to work at the end of rendering, on the entire image buffer. This would take some extra CPU memory, but it requires fewer passed than it used to and we are loading those into memory at the end anyway.
Then OpenImageDenoise could then be integrated outside the compositor as well, and the Cycles denoiser could become available in the compositor.

Can I propose such a thing as a feature request, then? Can't see any intent on choosing between "render size" and "scene size" if both are exactly the same. Instead can be very useful in some cases (undistorting footage in vfx) to render at a higher size (fixing camera sensor scale accordingly) and then use the scale node set on "scene size" crop the image to the intended scene size without complex calculation in the crop node.

Ignore my previous comment, I'm not sure what's going on here. Either Affinity Photo and LuminanceHDR both have broken OpenEXR implementation or Blender creates file that don't follow the spec. Affinity Photo can open the files and reads both RGB layer and alpha, but fails to save the data on export resulting in a blank alpha. LuminanceHDR complains that it can't find RGB data and refuses to load the file altogether. This happens for both your supposedly broken file and .exr files that can be properly read in Blender.

Robert Guetzkow (rjg) added a comment to T66515: Loaded OpenEXR file is displayed all black in 2.80. Looks fine in 2.79.

I've got the same result in 2.79 and the current master build. Both show the broken result. Since loading your .exr file in an external image editing application and saving it as .hdr or .exr doesn't fix it, seems like the alpha hasn't been properly tagged in the file.

Sebastian Parborg (zeddb) triaged T64052: Compositor constanttly crashes on particular input frames as Needs Information from User priority.

The issue is that the pictures that doesn't render contains pixels that have a glitched pixels (pixels that have a very high value).

Sebastian, no, they aren't. They are EXR multi-layer files, and they have source image in 'Render layer', and a pitch-black result in 'Composite' layer. In the image node there is a switch, where you can choose the 'Render layer' to see the image. By default, when you open a new file in the node it selects 'Composite' layer, which is wrong, so just select 'Render layer' in the combobox below.
Thank you for your attention.
