The longest thread at a hacker space I frequented was fighting over adding a 418 status to the mainline iot kettle stack.

The argument went that a kettle is not a tea pot since before adding a tea bag you can use the hot water for anything, including instant coffee. Someone added a tea bag dunker to the kettle. People started complaining about taking away choice by forcing everyone to use the kettle as a tea pot, so I added a empty tea bag as one of the selections. The argument then went that since it can load empty tea bags it is not a permanent tea pot even though it is mostly a tea pot so it shouldn't include 418 as per RFC 7168.

The last I'd heard of it, they had added peristaltic pumps that can be accessed individually, so if you sent an HTCPCP request to the tea designated pump for coffee it would return 418, but if you sent it to the beverage server it would route your order to the correct pump.
