From feedback such as %xFLWjn3... %EScsW7M... %tAMTiaq... %ud0UEgh..., I am thinking maybe to change the default behavior for git-remote-ssb and git-ssb-web to accept git updates to a repo only from the repo author (the original behavior), rather than from anyone you know (the current behavior). But what about people who have been making use of the current behavior for collaboration? Offer a choice to the fetching user for the different behaviors? This could be done as a config option and/or querystring parameter on the repo URL. Would that be an improvement over the current situation?
I will consider implementing proposals in this area that are clear and have substantial community support.
