I tried Ghostty for a few months, but found that it had the slowest launch time of all the terminals (NixOS) - we're talking seconds instead of tens of ms. Sadly, it looks like the launch improvements here are for macos.
gdbus call --session --dest com.mitchellh.ghostty --object-path /com/mitchellh/ghostty --method org.gtk.Application.Activate '{}'
I like foot but don't mind waiting a few tens of ms in exchange for kitty's graphics.
