I just configured my Gmail IMAP account in Mail.app. In the Settings > Labels section of Gmail, I unselected the "All Mail" label. In Mail.app, I chose the Gmail > Trash mailbox and then "Use this mailbox for Trash" from the Mailbox menu, and did the same for Spam and Drafts.
Now there are no mailboxes listed in the Gmail mailbox, but it still appears there at the top of the mailbox list with a little triangle next to it. When I click on the triangle to expand, there's nothing in there - but the mailbox won't go away. It's an off-white color whereas all the other mailboxes are the standard bluish color. (See image below)
