As far as institutional memory is concerned, new is anything that hasn't been seen in a couple generations' lifetimes, certainly not 1000s of years. This is also why I included "recently en vogue" in my prior comment, I'm not claiming that this thought process has literally never been seen before. Just that some cultural phenomena display a back and forth pattern, with a timescale such that it will feel entirely new to the current population when it's out in full force. Further, the negative impacts of the extreme adoption are precisely what will push the pendulum back eventually.
Also I will clarify I am speaking from a US-centric perspective. Are you not in the US?
I have seen multiple academic circles seriously come to the consensus that innocent until proven guilty is not good as a general principle. This sort of thing IME occurs on mailing lists or in department meetings, and it has also ramped up considerably in just the last few years. I've never looked for literature on the topic, perhaps the institutions I am affiliated with just suck. But given the many others reporting similar sentiments I suspect there will be some literature on it as a broader phenomenon, at least in the US, down the road.
