NLEs don’t use GPU acceleration at all outside of virtual reality. even high-end encoders don’t touch the GPU.
the media kit is already the backbone of a much more robust video suite than any other open source editor project out (and most commercial ones)
This is … blatantly false. Where do you get your information?
It’s the exact reason the Radeon SSG even exists… https://www.amd.com/en/products/professional-graphics/radeon-pro-ssg
Also also why RED has their Rocket accelerator cards (though the SSG is a good bit faster than a rocket accelerator and more versatile).

I’m not an engineer, but Quick Sync Video was specifically introduced by Intel (from their Sandy Bridge CPUs) for video encoding and decoding and is exploited by many modern NLEs:
Indeed it can be used for draft quality output, decoding previews as well as for streaming things live, in the end you typically aways use a CPU encoder for the final one though.
the NLEs i use in order to feed myself, running on systems with no acceleration.
those exist, those are not part of most edit suites.
