What I request seems to be the same option as x11vnc's "-norepeat",

Title:
Super important feature req: QEMU VNC server: Introduce a keyboard
"norepeat" option!
Status in QEMU:
New
Bug description:
Hi,
A big issue when using QEMU's VNC server (VNC KVM) is that, when
there's a network lag, unintended keypresses go through to the QEMU
guest VM.
This is frequently "enter" keypresses, causing all kinds of unintended
consequences in the VM. So basically it's extremely dangerous.
This is because the VNC protocol's keyboard interaction is implemented
in terms of key down - key up events, making the server's keyboard
autorepeat kick in when it should not.
For this reason, it would be great if QEMU's VNC server part would be enhanced with an option such that when a VNC protocol key down is received, then locally that is treated as one single keypress only (I don't know how that should be implemented but I guess either as an immediate key down - key up sequence locally, or key down + key up after say 0.05 seconds), instead of waiting for the key up event from the VNC client.
Thanks!
