I'm curious what you mean. I have been accessing Macs remotely over SSH and VNC for like 20 years and it's always been easy and as performant as the network would allow.
Host resolution automatically matches that of client, image quality is great, framerate is decent, latency is minimal. The host creates virtual screens for the connection so connected screens don’t light up and the machine remains locked to anybody accessing it physically too, which is a nice privacy assurance.
