repairability means jack shit if it doesnt get supported a year later.

I think this will be Apple's plan when the EU forces them to sell devices with replaceable batteries. The EU says end users should be able to replace the battery without special tools, heat, solvents. It doesn't say the battery can't be DRM'd up the ass, or how long or what quantity of replacement stock should be made available.

So I expect Apple will do exactly that - DRM'd expensive batteries in limited supply. So even if you wanted to replace the battery you won't be able to get hold of one. Maybe they'll allow OEM batteries but in the typical Apple way - gimping the phone and putting scary warnings on the screen that the battery is not Apple certified, that rapid charge, screen brightness, or something else is disabled. Because Apple are dicks.
