Also radicle does want to tackle the issues / prs and other elements you mentioned as well.
And presumably the person hosting it will make sure that the computer hosting it is often on, for instance ISP routers and TV boxes are a good way to popularize it, since they often come with NAS capabilities :

(Notably, it also supports torrents and creating timed links to share files via FTP.)
- finding what the domain name is ? - resolving the DNS to an IP address ?
Radicle solves both problems in theory, but more the latter than the former right now:
- there is some basic functionality to search for projects hosted on Radicle, to find the right repo id (I expect this area will see a lot more activity and improvements in the near future), - given a repo id, actually getting the code onto your laptop. This is where the p2p network comes in, so that the person hosting it doesn't always need to keep their computer/router/tv box on, etc.
