I‘d also rather say that it was about hosting the code for free in the first place and then the pull requests, including the possibility to comment on code in PRs. I use the git cli (instead of some UI / IDE extension) for all interactions with the repo locally. But as soon as it‘s about collaboration, these platforms come into play.

I just quickly scanned, to find that there is the `git request-pull` command, before I wasn’t even sure whether pull requests are a git built-in feature at all.

Side question: does any code hosting platform allow to comment on lines of code outside of pull requests? I‘ve had several occasions where I wanted to ask, why something was written the way it was.
