The 1992 retrial was just a publicity stunt, right? After all, no mediaeval historians were involved.
Yes and no. Gilbert Prouteau was a mischief -maker, but he seems to have been sincere. He did no original research, but based his case on the writings of his predecessors, Salomon Reinach and Fernand Fleuret. There was much that was wrong with the retrial – for instance, overtly fictional material from Prouteau's novel was admitted as evidence. Also, it carried no formal weight: it did not officially overturn the verdict of the 1440 trial, as some accounts imply. However, the lack of historians was not particularly a flaw. Few historians have written about Gilles. His first biographer, on whom all subsequent biographies lean heavily, was not a historian. There is no indication that any writer has paid due attention to the contemporary documents since Bossard's day. In order to have a more informed opinion, any historian would have to have specialised in Gilles' period and to have looked closely at the trial record. It is unlikely that such a person existed in 1992; there are precious few even now. Mediaeval historians had nothing to do with creating the myth of Gilles de Rais and nothing to do with this attempt at unravelling it.

"History is something that never happened, written by a man who wasn't there."
You say he was tortured? But he wasn't tortured, he was spared that in return for a confession.
This myth is based on a universal misreading of the trial record. At no point did his judges offer to waive the torture altogether, merely to defer it until the next day if he cooperated. He was given a few hours to think about it, and made his first (out of court) confession that same day. His second (in court) confession was given the next day, in a rare evening sitting. There is every reason to suppose that he was tortured in the morning. That would have been the norm; torture was routinely applied merely to confirm a confession.
Not much more than two years after Gilles de Rais' execution, the King wrote letters asserting his innocence, using highly emotive language and claiming that he suffered "attentats" - outrages - in prison. Clearly Charles, too, believed that he was put to the Question.
It is vital to correct this error, since it is often stated that Gilles confessed voluntarily, at the mere threat of torture. This has the double effect of making him seem a coward and his forced confession a spontaneous effusion of guilt. Nothing could be further from the truth.
