Wool item entities trigger sculk sensors.

Can confirm.
But probably too difficult to fix

Every item does.

I also can confirm. This issue is important because if you're building a trap or a redstone contraption with sculk sensors and you accidentally misplace a wool block, you need to be able to mine the wool block without worrying about it triggering the sculk sensors. Currently, if the wool item lands on the ground it triggers the sculk sensors.

Also, perhaps a better title for this report would be "Wool item entities trigger sculk sensors".

This has been fixed for throwing wool items in 20w51a, see the blog post.

This seems to have either broken or been reverted and I missed it as wool and wool carpet items seem to cause vibrations.

That'd be MC-252258.
