Is your proposal related to a problem?
VNC's performance or security isn't the best at all and it could be better if we could use newer protocols.
Describe the solution you'd like.
QEMU allows to also use SPICE as a newer desktop protocol option that has better performance and security with the use of a password or even TLS encryption.
Describe alternatives you've considered.
I used VNC before but performance isn't that great.
