> I really wish, though, that package managers were more capable of differentiating between security and feature upgrades. If they were, we could run a rolling distro in “Debian mode” at will.

I missed his point here. Isn’t that what Debian Stable is? It is not like you do not get any updates in Debian. It is just that they are all security updates that do mot often bring new features. How is that different from what he is asking for?

He wants the option of switching out of Debian mode in order to get new packages that aren't just security updates.
