If you're not willing to open source your project yet but intend to, you should absolutely create an empty github repo. My chance of checking in on this project latter relate entirely to it being posted again & happening to see it. If there was a URL to a repo, I would have a far better time following up. In general, though: just open source what you've got! I see this as a "letting perfect be the enemy of the good" problem. I both appreciate the author's desire to have a high bar for what gets released, but also think that mindset is a lot of bad friction. Getting into the world earlier counts for so much.
