I have been using sourcehut for mercurial private projects for about half a year without any issues. Also have some a couple of public repos which I develop in Mercurial and then mirror to Codeberg. Only issue I find with sourcehut is that they don’t produce files for users to download. So, if someone wanted something from your repo and they don’t have git / mercurial they would be unable to get the files.

I’ve also been using sourcehut for a few things for a number of years. Haven’t had any trouble. You do need to pay a small amount per month for an account, but I don’t mind throwing a few bucks to support an indie project like this.
