Everyone moving to "battery must be replaceable without tools" doesn't do anything useful for most users. Yeah, now you can carry an extra battery on a camping trip, I guess, though you could also carry a portable USB-C charger and use it for more than just your phone. It isn't particularly useful that it doesn't take tools to replace the battery when it starts failing, five years after your phone was discontinued, if you can't find a replacement battery for that exact model.
