Just to close the loop, these changes have now been implemented in `master` and will be included in ParaView 5.9. Below is the output generated using `--help` by pvserver executable from the nightly binaries. The launcher options are list first, followed by the standard executable options (in this case, pvserver options).

```bash
> ./bin/pvserver --help
Launcher options:
  --print Print modified environment.
  --system-mpi Use MPI implementation available on the system.
  --mesa Use Mesa GL for rendering.
  --backend <backend> Specify mesa backend.

Available backends:
    llvmpipe
    swr

pvserver options:

  --client-host=opt
  -ch=opt Tell the data|render server the host name of the client, use with -rc.

  --connect-id=opt Set the ID of the server and client to make sure they match. 0 is reserved to imply none specified.
...

```

You should be able to test these out using the latest nightly binaries for Linux.
