and get into merge hell when you forget to push and have passwords added on two different binary blobs? no thanks. I prefer using something that was meant to be a password server
No. You misread my point. I never said you should replace Bitwarden and use a Git repository as a password manager. My point is about self-hosting in general, hence why I linked the recent GitHub outage.
If you can self-host a password manager, then in the case of GitHub [0] going down every month you can self-host your Git repositories yourself, especially if you have projects like wireguard [1] for example.
