Earlier quoted context omitted.
Agreed that the upload queue solves this problem, but, one thing about the current system is it lets people choose where on the continuum they want to be depending on their risk/reward profile.
FTA, "even make the queued releases available for intentional, explicitly volunteering beta testers to try out." Under the proposed system, you have to opt in to the insecure early releases. Rather than opting out of them. Which seems like a more secure default!
This is the wrong framing.
There's no free lunch here. Delays in publishing not only slow down attacks, they also slow down critical security patches. There's no one-size-fits-all policy here, you're at risk either way.
