Current standards require main lugs before the disconnect to be protected.

One with protected lugs might make a good addition to the gallery.

Panels usually are generally one of two varieties, MLO (Main Lug Only) or Main Breaker. This graphic shows both MLO and a Main breaker which doesn’t exist. Since the title says Main Lugs the main circuit breaker (labeled Main Service Disconnect) should not be shown.

I know which is what the OP referred too, but the graphic was not accurate.

It’s unusual in my area for new builds.

The graphic now shows 3 conductors to a subpanel.

Now that the image depicts a main lug sub-panel, the only thing missing is…

Just a neutral adapter lug to allow larger conductors to connect to the bus. Very common.

Not around here, hair cutting and other improper installations are more common.
