I have multiple chargers at my house, from old iPhones and iPads - some of which I've bought myself and some of which were provided by my employer (they don't ever want anything back when it's written-off after 3-years).
I also have many many extra chargers, mostly Anker, with 2 / 3 / 4 ports or USB-A / USB-C combos etc etc, so the number of chargers has kept growing whilst the number of devices remains fixed as they're traded-in or sold on etc. Some households may be operating on strictly one in / one out, but I doubt they're the majority.
At Apple-scale (hundreds of millions of units) it cannot not be a good thing for the environment if they ship smaller boxes with less plastic in them. Fewer planes, smaller trucks, less production, reduced energy. There are additional chargers going to stores separately, but the net number has to be smaller.
