Sourcehut is cool, especially their stance on open source collaboration. But the problem with them is that they have a high learning curve, you need to understand the git VCS in depth in order to be able to use sourcehut to the fullest, the reason platforms like github are used is because they take little to no skill to use, everything is done through the github frontend, merging, merge conflicts, reviewing code, creating branches, making issues, replying to issues.
You do not need to worry about the git patching, you do not need to worry about emails etc, its all done through a centralised platform, which for a lot of people (especially proprietary developers) is amazing. If you want to go full elitism sourcehut is a good way, sourcehut + gentoo even better xD But if you want nim to be publicly supported, you will want an easy to use platform, and therefore codeberg or your own hosted gitea instance would be ideal!
