It's a good initiative. Next step: everybody realizes that researchers are just random people like everybody. Maybe that could kill any remaining imposter syndrome.
A rejection, although common, is quite tough during your PhD though, even ignoring the imposter syndrome, because in a short time, you are expected to have a bunch of accepted papers, in prestigious publications if possible. It feels like a rejection slows you down, and the clock is still ticking. If we could kill some of this nefarious system, that'd be good as well.
