I don't know about that. If they relied on aero development, then the F1.09 wouldn't have had such an amateurish front wing to start that season. I believe the rumour was that BMW was relying too much on the new KERS and flexible front wing technologies and had built the car around those functions. They had to build a B chassis half-way through the season (with a resulting performance improvement)once it became apparent that KERS wasn't all it was cracked up to be. Mind you, the FIA making KERS optional didn't help, as some teams had completely abandonded the idea (to those teams' advantage), and focused more on the DDD. If KERS had been mandatory in 2009, the pecking order would have been shuffled up a bit (certainly Brawn wouldn't have dominated to the extent that they did).
