Everyone moving to USB-C was the same standard, though; now you can use the same charger with your phone, laptop, tablet, other random gadgets, etc. If you forget your charger you can buy one virtually anywhere, or borrow someone else's, since they're all the same.

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.

You could already use the same charger with nearly everything. It was the cables that were not necessarily USB on the device end.

Apple for example as far as I can tell has used USB chargers for everything (phones, tablets, music players, headphones, Apple TV remote) except laptops since sometime in 2012. For laptops everything introduced after the last MagSafe 2 laptop in mid 2017 has used a USB charger.

Usually there are compatible ones that still give you some juice for 1-2 years at a small fraction of the price (of the original one).

If you worry about that, you can always buy an "official" battery in advance to be used 4-5 years later.
