What is the endgame here? Obviously "heightened security" in some kind of sense, but to what end and what mechanisms? What is the scope of the work? Is this work meant to secure forges and upstream development processes via more rigid identity verification, or package manager and userspace-level runtime restrictions like code signing? Will there be a push to integrate this work into distributions, organizations, or the kernel itself? Is hardware within the scope of this work, and to what degree?

The website itself is rather vague in its stated goals and mechanisms.
