OK, that's for sure not a small list, indeed...

I just had a look at a few readmes, and it seems my sampling was not
that fortunate:

    board/acmesystems/aria-g25/readme.txt
    board/acmesystems/arietta-g25/readme.txt
    board/amarula/vyasa/readme.txt
    board/asus/tinker/readme.txt
    board/csky/readme.txt
    board/orangepi/orangepi-plus/readme.txt
    board/raspberrypi/readme.txt
    board/warp7/readme.txt

And surely, we do not have that warning in all the readmes we have a
"sudo dd":

    $ git grep 'sudo dd ' |wc -l
    72

I too believe that such a warning is superfluous. Working with things
like Buildroot really requires a bit of preliminary knowledge; we can't
take everyone by the hand and we should probably require quite some
prerequisites...

Yeah, the might sound haughty or elitist, but we have to draw the line
somewhere, and I believe usage of 'dd' and its consequences are below
that line...
