Bomb ID was never intended behavior, so the dev removed it. That’s all there is to it.
You have so many low cost ways to dodge or disable traps. Levitation, any teleporting item (fadeleaf, blink stone, etc.), aqua blast, trap reclamation, chain. Even blast wave over traps is possible at +1 or above. Losing one way to help identify equipment really isn’t a big deal. Stone of Disarming is arguably the least creative and interesting way to play around traps. Also, the main draw of the monster house secret room isn’t the meager skeleton drop.
Bombs not working on barricades is a bug, which is fixed in the non-beta 2.5.3 release.
Sheep stone and Swifthistle seed do work, as mentioned. Hourglass if you had it yeah. Just kiting a mob into it would work, I don’t think Disint traps destroy equipment anymore.
Was about to say Aquablast, but it does use (1/8th of) Levitation.
