This would be the why of that acquisition as this needs a more integrated UI. Guessing by the speed at which this came out, this was in the works long before that acquisition.

it is not even clear *if* they are going to buy windsurf at all. And thats a big if. This might've just been the 'why' that deal is not happening.

This probably came out to beat Google I/O or something similar - odd Friday release otherwise.
