That is not what that says.
It says those airframes have (an) extra oven(s) on-board compared to the Embrears. Not that it was added for BoB.
The 737s for example have a total of 7 ovens (3 front + 4 rear) and the A321neo has 2 (1 + 1). The Embrears however each only have one, and no space to expand this.
