USB-C charging law in the EU.

You are absolutely right when it comes to single use consumer power tools. Even better than integrated charger on the pack, would be integrated-battery-and-charger-within-device, as I said above. All of this from USB-C with a crappy plastic cap, which would be lost around the same time when the DC motor brushes wear out or a plastic gear snaps. It would be good for drilling a few hundred holes and driving a few hundred screws, during a year or two, and charged like 5-10 times. Amount of e-waste is minimized when everything breaks down at the same time, and modularity (and overhead caused by it; e.g. battery connectors and separate plastic casing) is minimized.
On the other hand, in mid- or high-end power tools which see real (not only occasional) use, professional or home (e.g. larger renovations), these large dedicated chargers for swappable packs last for years, are used a lot, so not an e-waste problem.

Like this one that’s been around for years?

I have seen those before and would have declined such a standard for the same reason of poor ergonomics that I declined everything except the Milwaukee M12 standard.

Not a true alliance either, it's just one large corporation and their compatible sub-brands are not competing with each other, they are just for different fields, most never-heard niche.
Real compatibility alliance would mean e.g. that Makita, Bosch, Milwaukee, Metabo, Panasonic (or whatever is their current name) etc. power tools would have cross-compatible batteries. Not going to happen by the free market.
Think about it: their "alliance" claims compatibility to over 300 machines, but to compare, Makita LXT alone says they have over 325 machines. This 300 is the magic number of power tools for any single manufacturer.

It's certainly not a single corporation. However I suspect most of them are under umbrella of the same holding company and others are not really tool producers but sell rebranded tools that can be used with other products they actually produce. Fischer for example.

Then please don't try and pass a 5V input boost converter off as a 48V input buck capable of safely charging and balancing a 5S pack at 8A.
You've not spent a lot of time working with power tools in real world conditions, I'm certain.

This is a 3S pack charger with PD. You seem to go for a hyperbole immediately, so I also should clarify that it also not enough to charge an electric car. I have half a dozen battery powered power tool at home, all of which could be USB PD powered, and this is applicable to 95% of the people.

Of course it could - given enough time. Think about the possibilities of USB-C charging your EV at 200W; at 200Wh/km, that's one km charged every hour!
