It’s not “sad”. Nothing better has been conceived to replace it.
If it ain’t broke, don’t fix it.
Heck, I can come up with an idea for one right now.
For instance, replace the gun with a submunition dispenser. being able to drop multiple precision guided munitions (PGM) might be a good replacement for the gun. You could carry a lot of 25 lb. bomblets for the weight of the gun and ammo.
