Heterodontosaurids

Hello everyone, so today i've been reading about heterodontosaurids(in Dinopedia by Darren Naish) and there were mentioned 2020 study by Paul-Emile Dieudonné and his colleagues about pachycephalosaurs being within heterodontosaurids, that there's are certain affinity between these family's of ornithischians. And then i decided to look into wikipedia page for Ornithischia and there's was a tree showing heterodontosaurids being placed in pachycephalosauria. And it got me thinking since in book nothing was mentioned about it neither did i find something on reddit or internet, did this classification ever become 'popular' or have it been accepted by some other paleontologists, i'm simply curious how much support did the work of Dieudonné got.
