They removed other non-networking features too. E.g. even autotype was removed. At that point why not just store your passwords in an encrypted notes app?

I use KeePassXC, but not any network features or autotyping, because I like the password generation and because the interface is nice. I previously used Vim's old encryption feature (since removed I think?) and I think KeePassXC as I use it is a good upgrade from that.

Just use https://www.passwordstore.org

Or maybe just fork the project instead and let users who want these features use the package the way the authors intended.

There are multiple KeePass implementations. The people using this one are doing so because they want its features.
