He never claimed refterm was a fully working terminal ready to use. He said it was a renderer. The entire point of refterm was:

    <casey> Windows Terminal is slow at rendering things
    <microsoft> Yes, rendering is a hard problem worthy of a doctoral research project
    <casey> No it's not, you literally just use a glyph atlas
    <microsoft> You are naive
    <casey> *writes refterm to demonstrate glyph atlas*

You keep complaining that it's not a fully working terminal. Casey, on the other hand, writes:

"These features are not designed to be comprehensive, since this is only meant to be a reference renderer, not a complete terminal."

Exactly. Therefore you cannot compare a renderers performance with some other that has a fully functional VT backend attached. The comparising result is meaningless. His renderer is good, but the VT throughput performance claims he makes are wrong. For that to be fair, he should not take shortcuts in functionality.
