That 'edge' was no doubt included, to allow emergency racking. Replacing the BG2.0 rear sight with the BG1.0 makes the issue go away, and gives a better sight picture.Found out a new to me "issue". Using an outside the belt holster and practicing drawing showed me that the front of the rear sight is sharp. Using a pocket holster, this never was noticed. They are very sharp!
I agree on your sentiment of WHY? I'm not complaining but asking WHY?
XS Sights makes a few variations on their rear sights. Several would allow the back plate to remain exposed. However, they said they will not be making this variation for the BG2.0.
I have not taken my rear sight off. Will the rear plate that secures the striker remain in place when the rear sight is removed? That could be a factor.
I've cleaned striker channels with polymer safe gun cleaning sprays to wash them out and then blow them out with 125lbs of compressed air. Seems to work pretty good.

I am probably controlled by my own "feeling better about it" when it comes to cleaning a striker.
