Nonsense. That's simply your interpretation of it. I'd argue -- if you're going for that -- that one of the dates I've outlined above for the creation of that image is as meaningful, as those pin the initial software releases to at least a reasonable point in time.It is pretty clear that "installing", in the context of Rasi Pi OS (which is what this sub-forum is about) - and given that Raspi Pi OS has always, since its inception, been installed via an image dump - is the act of copying that image to the SD card (or, in later years, to some form of USB-connected hard drive).
That dumping of the image might be done with any of a range of tools - dd, unzip, cp, cat, "Raspberry Pi Imager", etc - but it boils down to the same thing - dumping the image to the SD card.
If you're fussed, just add 'touch /etc/installed-on' to your list of commissioning tasks and be done with it. It's as good as any of the other metrics.
And, for the record, your definition would mean that none of the last half-dozen or more Pis that I've 'installed' have been installed.
