The same commit caused me problems in certain games which contain Securom activation: after the commit Securom no longer accepted the existing registration info (stored in the registry and on the disk, under /users/your_username/Application Data/Securom directory) and it required a new activation. It is quite an annoying problem if the game/app has activation limit (Securom usually allows 3-5 activations with the same serial).
Well, the SID is stable now, it won't change again when you create a new prefix, which should make such registration data portable across prefixes.
