If a structured crafter makes something that can't be placed as a block, and there's not an output inventory to put it in, it should try to dispense it rather than unconditionally dropping it as an item. For example, it should drop minecarts as themselves instead of as items.

Not a bad idea.

@CplPibald The redstone pulse is a good idea.

This isn't always what you'd want. For example, you might not want want to craft TNT this way.

The crafter could simply trigger a strong redstone pulse each time it crafts something. Then you could make this same effect by putting a dispenser in front of the crafter. Each time an item is crafted it would insert into the dispenser and immediately trigger it.
