I did give the rea plugin a spin yesterday to restore the source for something I made in the 90s where I only had a partial backup of an old version of the code. It was able to get to a byte identical artefact but built with GNU as and all the artefacts split out into pngs.
It took a few hours for something that would have taken me days if I'd be actually been inclined to spend the time. I can totally see the appeal of offloading a boring and laborious task to an LLM agent that will just chug through the stages.
But what is the purpose of these decomps once done. Are they intending to do something interesting with the result? Study, tweak, remix?
