OK. I guess I had figured that removing it from the director would also kill any active proxy sessions, but that's obviously not the case.. it just removes the host from the list and any mappings from the hash.

Maybe something as simple as killing any login proxies that are talking to the selected backend, or are proxying for users that are mapped to the selected backends? Or maybe the Directors don't know enough to do that? I'm thinking like 'doveadm kick' for proxy connections, since who/kick doesn't work on the Director, just backends.

While I'm making a wishlist... 'doveadm director status <ipaddr>' to show list of users mapped to a host? Or maybe just 'doveadm director status -v' to show list of users instead of just user count.

You're right. I see that FLUSH just does the 'remove any mappings' bit that REMOVE does, and ADD with a 0 count is effectively the same as removing it from the list. For some reason I was thinking of this as 'flush out (kill) any active proxy sessions'.
