I mean people use IDA for decompilation instead of reading assembly directly, and that's counted as as valid reverse engineering. Why shouldn't throwing it an LLM count as well? I think reverse engineering is one of the fields where "anything goes", it doesn't matter how you get to the answer as long as you get there.

I do agree that the notion of difficulty needs to be recalibrated though, seemingly impressive RE tasks can now be done trivially with LLMs.
