Oh, didn't occur to me it may work that way with the unfinished areas, it was really interesting to peek into the next update's area! Is there a way to visit the toy warehouse area like this?

No there is not. But you aren't missing out on anything. The area is just a few tiles larger than you can see from behind the barriers and it contains nothing new besides spots for a future pooltoy packing machine, which isn't even there yet.
That way everyone knows it's not expected to be present in the current versions, but also you still have access to the area in case you want to loop nearby enemies instead of shooting them. And you also get a few thought bubbles and a note.
