As the page does not discuss the motivation behind the API, does anyone know why this is ”native” API and not just a generic image processing script implemented with JavaScript / WebGL / etc.?

At this point in time it's a pain point for me that Android devices don't usually have built-in QR reader software. I can tell iOS users to just "scan the code with the Camera" app but I have to tell Android users to find a QR scanner app on the app store. My experience with an actual bottom-of-the-line prepaid phone was that the first QR scanner app I downloaded from Google Play worked right the first time but I had…
The Google camera app does support QR codes FWIW, but I don't know if any other vendors except Google use it.
Recently, we stumbled upon some cheap USB keyboard emulator 2d scanners that can pick these up very reliably. For our product/customers, this is a viable path. We have tested probably 30 different webcams by this point. The only 2 that are as reliable as the handheld CCD scanner are the iPad and my Canon DSLR tethered to my PC in automatic mode with a macro lens.
Resolution is a factor, but so is frame rate and environment. You have to consider the full UX stack. Someone is required to physically position the barcode in a particular way with certain lighting constraints, etc. With a handheld CCD scanner, you get a laser guide for precisely what distance to go for, and an ergonomic experience that is much more conducive to successful scans. Most offer on board illumination, so even in a pitch black room you will get a successful scan.

According to this documentation, yes, it returns the raw value encoded in the barcode. What it does not appear to do is further decode the raw value into logical data. E.g. data matrices commonly contain GS1 element strings that are not trivial to decode. There are libraries for that, though.
Arguably, as a Barcode Detection API that's all it should do.

Honest question: for what reasons do you ever need to scan a random QR code? I think I've used them to sign in to some apps (eg, WhatsApp) while logged in on a PC, and other than that exactly 0 times. The Google camera app does support QR codes FWIW, but I don't know if any other vendors except Google use it.
- Lately it's been pretty common for restaurants to replace their physical menus with a QR code on the table that links to their online menu.
- When I've taken COVID tests recently, the site gives me a sticker with a QR code that links to my results page.
- I encoded my wifi network/password into a QR code and printed it out, so guests can just scan it to join, rather than have to scroll and find the right network and type in a password.

Native code allows for performance gains that a script (even a performant one) may not be able to match. After all, this is fundamentally an image processing problem, one of the more computationally expensive things a browser has to do.

So my use cases are (1) I am demoing the cards for people, and (2) I give the cards away for free (If it wasn’t for the supply chain crisis I’d be creating a new card design every day) or put up an installation somewhere and people interact with them. Either way I want it to be very easy for people.

In general, assuming you have an easy-to-use QR scanner, it's easier to scan a QR code than type in a URL on a phone, especially a complicated one. A couple examples I've run into recently: - Lately it's been pretty common for restaurants to replace their physical menus with a QR code on the table that links to their online menu. - When I've taken COVID tests recently, the site gives me a sticker with a QR code that…
You can put up a QR code to point people to the web app which controls the IoT functions in a space, music system, etc.

They're also in some restaurants where you can get to a menu to order from your phone.
You also scan QR codes for use in two factor authentication apps.
Covid has normalised QR code scanning in Australia - we have to do it at certain venues in order to show our vaccine passes.
