Yes, it can. The link I included does just that and adds a helper to
see if the slot is defined and includes it if so.
Perhaps it's just semantic sugar but content_for makes more sense to
me than slot. I'd always associated slots with components. Not for
lightweight content. The example linked also adds a default if the
slot's content isn't defined, which is nice for body IDs or other
persistent elements that you occasionally need to override..
