I have been setting up a matrix server for my work but it's a mess for people who just want a slack alternative. I understand that federation is the whole point but what about use cases where that is not the most important thing? The weirdest thing about a synapse/element combination is that there is no real admin panel/ui. And even if there was, imo. admins don't really have the same level of control as a slack admin has, but that is needed if it's supposed to be used in a corporate context. After self hosting a huge stack of synapse, element, jitsi, matrix intergration server, matrix identity server, bridges etc... (it is seemingly never ending) just to get a truly self hosted matrix server.. i am actually ready to implement my own. It just has to implement enough to be a useful slack replacement.
