I hope he targets something better than a vt102 (going for 520 like Zutty would be good) and remembers to do extensive checking with VTTEST. Blog post from the Zutty creator about correctness: <https://tomscii.sig7.se/2020/12/A-totally-biased-comparison-...>
This is promising: https://mitchellh.com/writing/ghostty-devlog-005#xterm-compa...
(I have also been bitten by terminals calling themselves `xterm-256color` or some such thing while not being remotely xterm-compatible; GNOME being the worst offender, as usual. My daily driver is mlterm¹, which is pretty good in that respect² — its main downside for me is its idiosyncratic font configuration, which is tailored for multilingual flexibility, not the English-only programmer.)

Zutty is useful for only one thing: passing VTTEST. I've tried it and it's unusable as the terminal you want to rely on to do everyday work.
I’m really interested in Mitchell Hashimoto (founder of Hashi Corp), terminal app he’s developing called Ghostty.
His latest blog post on it, also related to latency & benchmarks comparable to Alacritty.

For those interested in the tech, he’s developing it with Zig, uses SIMD extensively, and it’s cross platform. Can’t wait for him to launch it.
