but whos going to implement them?
That's precisely why I think we should use an existing
implementation if we were to use this at all, e.g. GitLab. I don't
know any implementations that only adds threading and nothing
else.
On notifications, I'm pretty sure the default notification
setting is to receive all issues as notifications for repositories
you've created and all activity for issues you've created. There
wouldn't any more problem with setting up notifications than what
we already have.
