We're trying to limit open GitHub issues in order to better track planned work and features.  \r\n\r\nThis doesn't mean that we'll never ever implement it or that we will never accept a PR for it. A closed issue can still attract upvotes and act as a ticket to track feature demand\/interest. \r\n\r\nThank You to you for taking the time to create this issue!"
