"make a choice" section in clockwork level [not sure which one(s)]

I think this was added in one of the recent updated because I had never run into it before. Correct me if I'm wrong. But the choices I've seen where:
Room of crowns vs. Room of heat
(in my instance the crowns seems more appealing -- 450 worth vs unknown amount of heat, maybe equivalent but I usually need money over heat)
Room of green treasures Vs. Room of heart boxes
(didn't need the health so I went for loot)
And you have to step on one of two party buttons to pick a room, doing so will block off the other.
I hadn't seen anyone mentioning this in the forum, maybe I missed it, but I thought this was a nice little tweak to the level. Nice to have a little variety like this added to levels.
So was this indeed new or had I just somehow missed out on this feature for a few weeks?
Haven't seen this before. Looking forward to see such things now! :D

Yeah I wish I could recall WHERE i saw it, probably mechanized mile or wild path or something.
Would make sense then if its rare and not new, since I've only seen it twice so far, but I did see them close together when I did.
I imagine there might be other Room vs Room options too then, though can't imagine there being too many other combos. :)
Ehehe...what about...
Quicksilver slimes already 'quickened' or grease slimes already 'on fire'?
@ delcore1
I would choose option 3 in that case.

haha that would be interesting to unleash a certain type of monster from their cage for whatever rewards they might bring
maybe we need a monster zoo level that has all sorts of doors that you can optionally open like this lol
I've run into the Loot Boxes or Heart Boxes choice a few times.
I was lamenting to a friend that noone ever chooses hearts so it isn't that interesting a choice.
I was thinking a more interesting choice would be:
Four unbroken treasure boxes
vs
Four broken treasure boxes
Do you go with the known quantity, or risk opening door number 2 which could just drop a ton of vials/health max items instead of all the crowns and heat you could have gotten from the known quantity.
Could be interesting :)
They've had it for a while. Though from what I've seen so far they are a bit rare.
