The only thing Samba is really great for is interop with Windows. If that’s not an issue, Dolphin can browse SFTP directly by adding it as a network share (you may need to setup a password-less key pair to avoid having to login). SSHFS is a similar option and works even if the client is totally naive (it just looks like any other mounted FS).
There are definitely some places the CGI could be improved these days (thinking distant group shots) but yeah, it’s incredible how well everything else holds up 20 years later even in 4K.
