...and you could probably shave off 20 MB from Ghostty because it is distributed as universal binary (does that even make sense in 2026)?

    > ls -al ghostty
    total 81992
    -rwxr-xr-x  1 floh  staff  41979664 Mar 13 17:08 ghostty
    > file ghostty
    ghostty: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable     x86_64] [arm64]
    ghostty (for architecture x86_64):      Mach-O 64-bit executable x86_64
    ghostty (for architecture arm64):       Mach-O 64-bit executable arm64
E.g. the complete app bundle is 62 MB, of that the executable is 40 MB, but that contains both ARM and x86 code.

Performance,startup time and memory usage matter more in terminal apps than almost anywhere else.That's why people react strongly to this.
