It seems this is actually that the big plus does not any more have it, but the small plus under rooms has it. Which I only realized as tulir mentioned it. This is kind of confusing as the natural action goes to clicking the big button, which is at the space header and not at the room header.

Adding on to this issue, this "Add -> + Room" button will actually only allow to create a new room in this space and not an existing room. The equivalent "Add -> + Space" button in contrast offers "Want to add an existing space instead? Add existing space".
