The former is securely authenticated and encryption, the latter is often
not - unless using the GTK-VNC + QEMU  VeNCrypt extension, but I can well
imagine there's plenty of people who don't do that, particularly if they
are a SSH GSSAPI+Kerberos enabled environment.

Both are valid deployment use cases and we shouldn't presume one vs the
other, although obviously we can make recommendations.
