The thing about Unisex restrooms though is that they have capacity for one person at a time, since that's kind of the point that the one person goes in and they lock the door behind them. The Gender Discriminatory bathrooms remove the need for the lock, so they're often swing door style. That's how I've always seen it done.
I've never seen a bathroom stall without a lock on it. Where do you live that this is a thing?
I have seen multi-stall unisex bathrooms, though.
I think there's a communication/region(?) breakdown...
Here in the US, you have restrooms with usually unlocked doors (push/handle style, no latch). Upon entering this room, toilets have their own privacy panels with slide latching doors. Urinals are mostly setup with privacy panels between them.
The exception to this rule is the single occupant restrooms which have a locking door.
