There are other teams than corporate IT teams. There are other non technical groups that would greatly benefit from e2e groups like Signal has, that would love the added luxury of self hosting/non centralised hosting. I can easily envisage different groups wanting these things. Some do not want the 'historical' chats to be kept, & server side search is not really relevant in those cases. Of course, some will. If we think of more than tech teams, it's easy to see these features as being vitally important. So while bugtracking, CI, bots, etc, etc is important for you and I, there are groups and communities where such things would be met with bafflement as to their purpose.
