Those tend to say things like "This benchmark is not sufficient to get a general understanding of the performance of a terminal emulator. It lacks support for critical factors like frame rate or latency. The only factor this benchmark stresses is the speed at which a terminal reads from the PTY."

So although those tests may be more extensive, they're not "better" in every regard.

Of course it's perfectly reasonable to want a benchmark that people can run without needing to build any custom hardware.
