The blender code is in lockstep with Bourke. Future changes in his format relate to video walls.
I agree on S3D. I can fake it by dti with a fov 120 degrees. The whole market is in flux, may take a few years to recover.

The trick to get me to put custom dome warping into Chimera is to give me an example warp file with completely clear documentation on the format of the file and how the warp is defined, and throw in an example unwarped (fish eye) image and warped image. With that I could probably put it into Chimera in half a day. The current Chimera dome mode computes a cube map and all that is needed is to set up some warping geometry defined by the file and texture map the scene onto it.
Chimera currently does the full hemisphere fish-eye interactively which is what we have been using for animations.
Let’s get things working in mono before we worry about stereo.
