I still think it's weird. Walkie Talkies had hot swap batteries. Now we have to use an external battery pack. Through what sleight of hand did that happen? Somewhere along the line we switched to glued in batteries. If I have a choice I'd choose the hot swappable battery... but I don't.
You can get some devices that still take AA batteries. Those are great for charging externally and swapping instantly.
How DIY'able are devices with 3D displays? Can AA batteries replace onboard batteries?
