they definitely listen and fix stuff pretty quick in the beta. But this one… doubtful. It’s also a supervisor update not a core update that introduced this check so it wouldn’t have come up in the beta testing anyway. The discord beta channel is only for core. There are dev channels which is where you could provide supervisor feedback. I doubt anyone said a word about this for the reasons I stated. I know as soon as I saw the warning on a dev instance I play with that I immediately changed the password and despite the protestations and justifications people come up with there is really only one solution for that!
What I am saying is probably most beta testers and devs never saw it as a problem.
