Unfortunately, the K4 is using the same code tree as the K2/K3, so it inherited the same defaults we've been using for over four years... FWIW, since that's what I'm used to, I do the exact opposite on my K5/PW: I switch to 'old' default
.
That said, I completely agree that on devices with a working USBNet in diags, it's stupid and confusing to use a different default in main. In fact, when I first read this, I though 'wait, I switched the default, didn't I?' But nope, that was on the K5 ˆˆ. There are already a couple of tweaks to the default config made during the install process specifically for the K4, so I could probably switch the default for new installs, it'll just make the doc potentially a bit more confusing.
