I got this set up and working in basically 5 minutes. Going to try to set it up at work. Super cool! It seems like the open source version already has a bunch of features, how do you plan on making sure you can sustainably support it?
That is an orthogonal solution to SSO. I have many apps in my home lab. It doesn't make sense to have individual credentials for everything, even if it is effectively free to keep track of them. Rotating dozens of passwords (even spread out over time) is not my idea of a fun day, nor is supporting individual logins for friends/family who use the apps in my network.
SSO is the quick and easy way, especially when other people are involved.
