Harichuck & Harium: Opinion on Hari mods

Recetly discovered two backport optimization mods of Lithium and C2ME by Hari, though I don't trust their mods yet. They appeared out of nowhere and apparently add nothing new, aside from the changes from the upstream. I am interested in new ways to squeeze the last bits of performance out of my modpack for 1.20.1, but Hari mods seem to just copy the work of other developers and publish them under their account. What do you think?
