SA advised that it regulates fuel consumption more conservatively at that point. Its obviously not the same as limp low-power mode.

The reprogramming just delays the HPFP failure as BMW owners have confirmed.

So basically, it says the same thing you have been inserting into every one of your posts. The software update is the most efficient time-friendly fix for the pump
at the moment for N54 owners. They began production in 2006. A good majority of them are going to be problematic. A newer pump for every single pump that "fails" is not smart; given the large amount of 335i owners that have problems with them, this would not permit them to drive. It just doesn't make sense to continually bash the software update because of this.
And I know you are an extreme advocate of a permanent HPFP fix. Way to go
