As someone else pointed out, the short story is cost. Mines are cheap, make them more advanced and they are not cheap.

That said, even if the trigger is disabled, it's still an explosive device and should still be cleared (or never placed in the first place, as the Ottawa treaty says which the US, China, Russia, India and Pakistan are not a part of https://en.wikipedia.org/wiki/Ottawa_Treaty)

The treaty also only covers anti-personnel mines, anti-vehicle mines are still perfectly fine (as well as other nasty shit like, anti-handling devices). The US has the right idea by mandating that all mines detonate after 30 days, even if it adds cost and complexity

Due to Russian invasion of Ukraine some neighbors exited the treaty.

Poland, Lithuania, Latvia, Estonia and Finland exited.

Ukraine has not officially withdrawn from the treaty, but ignored it. Last year they officially announced withdrawal.

Unfortunately anti-personnel mines are highly useful in case of war, especially for defender.
