It would be cool if there was a pipe with holes in it; or a grate on the end; any items that went through the grate would be dropped. If the grate were connected to a puller instead of a pipe- it could act like a hopper; picking up dropped items- but much quicker (at the speed of the puller).

Use Case: Auto Crafter

Say you want to craft a bunch of golden nuggets into golden bars for piglin trading.
One way to do it is to fill lots of chests and then break them with a crafting table nearby.
With a grated pipe though, you could have the items rain down on you instead.
The process could be toggled by having a sticky piston move one of the pipes out of the way and back in via a lever.

Thinking about it, this may be out of the scope of this mod, so I am closing the suggestion (If you still want to do it, go for it).
I was thinking about a block for Tom's Storage mod, that is kind of similar- but it treats the air below the pipe as an inventory that can be pushed and pulled from. That still falls under the scope of their pipe mod- but this suggestion feels like something that might be in a different mod, such as Kibe.
