Mandatory community visit while traveling Sandy Blight Road?

I was just browsing through the permit information on this page:

Permit page

And I came across this statement regarding the Sandy Blight Road: "Travellers on the Sandy Blight Junction Road must travel via Tjukurla Community where food, fuel and general supplies available at the Tjukurla Community Store."

No word if a mandatory minimum purchase is enforced. :) But seriously, has anyone been on the SB recently? Did you stop there, or does that seem to actually be enforced?

Judging by the map linked on that page, the visit may be unavoidable, as they show the route detouring over to the community, then back over to the actual SB.
