Well that information is classified ;-)
We've run some tweaking in our internal IPs to achieve better power / performance, and we don't want our competitor nor our customer messing around with the system's internal configuration. Of course if you are doing medical / aerospace / military application, you can always approach any of NXP distributors to liaise NDA agreement with NXP to get the detailed information.
Downsides : None so far. In fact, we have received good review from our major customers.
The reason why it's not enabled by default: Because we want to have the specification in the datasheet similar to the older generation (eg LPC111x/301, LPC111x/302, etc). Changing the parameter in datasheet would require our customers to do qualification testing again, and we need to sync our manufacturing site for the new parameters testing. So we'll let the power profile as option for customers who want it (or not wanting it for compatibility reason).
