Most devices & gadgets are rechargeable nowadays. The only thing I have that still requires batteries is a headlamp but even those are available in rechargeable varieties. House smoke detectors need a battery too.

You can’t just mix and match battery chemistry and call one superior. If you could, they’d all be inferior to a nuclear reactor in the right packaging anyway. But since you absolutely have to be pedantic about it, I’ll make this revision specially for you with emphasis in the right place:
And you can’t just allow for different voltage ranges without all the electronics also being adjusted for that.
Superior is a value judgment I wasn’t making there. You made a claim about cost and capacity between different chemistries (unless you meant something else by “rechargeable equivalents”), and I said it only holds up for cheap (alkaline) primaries under light loads.
I’m trying to share additional information, not win an argument on a technical point.
That’s true. The broader topic of long-term obsolescence ought to include device design though. Someone designing a device today that could potentially use AA batteries should think about whether they’re obsolete for the use case.
