They would be a minor "game changer" in that they are impossible to overlook by either side, unlike the old mine icons that could be missed on a cluttered map.
OTOH.... nothing at all is changed in the code so an undetected minefield remains Icon free until it is detected
I did try a red/black version and white/blue/black/red versions as well which are less eye-catching than the yellow
White skull on red OTOH works like the yellow on black in a K.I.S.S way
And there are alternates to that.... the word MINES added in white
and alternates to the alternates .. the word MINES added in Yellow
And alternatives to that .. the word MINES added in white with a yellow skull
