I've been setting up servers for everything ranging from IRC to Teamspeak, Exchange, and you name it. But how come setting up a Matrix server is still a science in itself?

Yes, I'm aware of the Ansible script, but should that really be the only somewhat reasonable option? When Matrix wrote " Matrix 2.0 a new chance if you gave up on us in the past".

I listened, but without a somewhat reasonable setup process for the server and the ongoing confusion in terms of clients, it hasn't gotten any easier to onboard to Matrix, unfortunately.
