And it’s really opaque. Would be fine if it were an open source package but there’s a lot of mystery behind how it’s implemented.

I don't find it that opaque. Even without trying to deobfuscate the obfuscated source code which Microsoft ships (I haven't tried but it wouldn't be hard) a lot of details about how it works become obvious just by reading its logs.

Of course, it is a pity Microsoft doesn't open source it. But there are some well-maintained open source alternatives, e.g. https://github.com/jeanp413/open-remote-ssh and https://github.com/F1yingWhite/fast-remote-ssh (I haven't got around to giving either of them a go–but I really should.)

They will never open source it. For the same reason Pylance etc. aren't open source and MS tries hard to prevent them to be used in VSCodium. Every one of their open sourced projects contains a closed source plug that MS can pull at any time that is one of the features that gives the project its unique selling points.

Exactly! Like if I'm admining a server what am I supposed to do? Message on a big slack channel and have everyone ignore me? It's easy when people are just logging in through normal ssh as I can put a big bright warning message on their screen that they can't ignore.

Also, timeouts...

Also, does anyone know if VSCode supports mosh?

Could just put this in /etc/bashrc.

    if [[ $TERM_PROGRAM = vscode && -f /etc/motd ]]; then
      cat /etc/motd
    fi

Assuming your users use the integrated terminal regularly

  cat /etc/motd >&2

please

Tried that. But I suspect you know why it didn't work

I don't

  >>> Assuming your users use the integrated terminal regularly

People don't use the integrated terminal regularly

I suspect vscode claims to xterm-256 and doesn't bother to identify itself in any other way

It does identify itself on my machine

    $ echo $TERM
    xterm-256color

    $ echo $TERM_PROGRAM
    vscode

I have looked for mosh support for a while and not found anything. It would drastically improve the connection experience in VSCode. My terminals never disconnect anymore, but the Code popups about your sessions needing to be restarted has drastically reduced my usage.

MOSH is not suitable for automated usage such as TRAMP, VSCode, sshfs, etc. It is only intended for interactive use.

To use mosh vscode would have to do OCR because mosh transmits images of the terminal

This is nonsense.

But so is the question. MOSH interprets all the escape sequences and uses them to decide what to send to the client. That way if you tail a log file and then get disconnected, you don’t have to download every line of text that was output to your terminal while you were away; it can just send you what is currently visible.

MOSH is strictly for interactive use; never ever for automated uses like TRAMP or VSCode or sshfs.
