Maybe it starts that way but once that's accepted as a thing the result will be increased usage of mines. Where before there were too many civilians to consider using mines, now the soldiers say "it's smart now, it won't blow up children" and put down more and more in more dangerous situations. And maybe those mines only have a 0.1% failure rate in tested situations but a 10% failure rate over the course of decades. Usage increases 10 fold and then you quickly end up with a lot more dead kids.

Plus it won't just be mines, it'll be automated turrets when previously there were none or even more drone strikes with less oversight required because the automated system is supposed to prevent unintended casualties.

Availability drives usage.
