Wayne, here's a past link regarding the spoiler:

While there has been a spoiler ( no pun intended ) in the past , it would be new for the current version of the car ( I hesitate to use the term COT ) . How will it work with the higher greenhouse etc.
One of the design objectives was to make it a bolt on replacement , no extra work or expenditure for the Teams, along with allowing the Teams to test and provide their feedback.
Maybe now the spoiler replacement schedule will be expedited or make sure there are no delays.
