Since there is STILL no way to view multiple email Inboxes at once, and in the only workaround "All Mail" view Trash-marked messages clutter up the list, I used this button extensively. The new UI just went from 1 click to 4x(!) the clicks for the same operation: 1) click to Trash 2) click to go to Trash view 3) click on the message again 4) click on "Delete permanently"
