Social/collaboration features are explicitly deprioritized by design; I think this is a natural consequence of srht being built by and for lone wolf developers.

It's not the case that SourceHut treats collaboration features as out-of-scope. Drew seems to draw a bright line between social and collaboration features, and intends for SourceHut to offer solid collaboration features, but without any hint of trying to be a social network.

From an old comment of Drew's: (edit: I now see Drew's comment was replying to you yourself)

SourceHut is designed to facilitate collaboration, of course, but it's done differently from platforms like GitHub and those that seek to emulate it. And of course it is more than a git frontend, providing tools specifically to facilitate collaboration such as mailing lists and bug trackers. SourceHut is an engineering tool, not a social network. It is designed to get your work done and then get out of your way.

GitHub is explicitly designed like a social network, and this is a design that we reject.

Built by lone wolf developers, plural?
