This is great, but a similar thread [1] was so recent that I think we should wait until the current post is no longer a follow-up (about which see https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...)

Can you email hn@ycombinator.com so I can arrange to send you a repost invite for this after some time?
