How is the "lock screen" entry in the menu not enough to show that the
feature is there?

Except it doesn't help, at all. The attacker seeing you leave has a whopping
5 minutes to START attacking your machine. As soon as he/she did the first
key press or mouse move (which takes less than 1 second), the timeout is
reset.
There is one safe and secure way to lock your screen, it is to click on
"lock screen" BEFORE you leave your computer.

Other replies in this thread have already explained why that approach does
not scale. Pretty much ANY application would have to inhibit autolocking, at
which point the feature becomes moot. There's hardly any application that
cannot display lengthy text and/or multimedia content that takes minutes to
read or listen to.

My point is that it's 2 clicks, i.e. 1 second, to lock your screen securely
(i.e., manually), so autolocking is useless.

As I already explained, the automatic locking actually DECREASES security,
because it mistrains users to not lock their screen manually.
