those warnings have no effect and happen on every system. You can ignore
those.

setxkbmap -print doesn't use the keymap directly as you'd expect. it uses
the RMLVO properties, changing a keymap directly with xkbcomp isn't
reflected in the setxkbmap output. so simply said: this is a false negative.

check with xkbcomp -xkb $DISPLAY xkbmap.out and compare that file with the
keymap before and after. where xkbcomp uploads the correct data and the
server accepts everything, the file will reflect the changes you made.
