How would you get security updates then? A week is a pretty long time to
wait, if, say, we had a header-parsing bug in Evolution that allowed
remote code execution.

It's a multipart problem. We need think in terms of "budgets".
A) How many times does the user get asked to interact with us to
update the system?
B) How many times does the user get asked to reboot?
C) How much CPU/IO/bandwidth do we use to install updates?
D) How many times does the user experience change in ways that might
confuse users?
E) How many times do we accidentally break the system?
[ budget == 0... ]
Exceeding our budget in any of these areas will make users unhappy.
Batching up updates to once a week helps with A) and B), and maybe with
E) if it means we do more testing, but doesn't help with C) and D).
