Why users cannot create Issues directly

I installed Ghostty. Found I couldn't search the text buffer. Found this issue[189] that was opened on Jul 6, 2023. Latest comment is from Feb 9:

> To be completely clear, it’s not on the “IMMEDIATE” roadmap[...] It’s absolutely on the roadmap[...] But as a passion project, we prioritize working on whatever we want[...]

The search function isn't even listed in the README.md's ambitious plan:

  The high-level ambitious plan for the project, in order:
  #  Step  Status
  1  Standards-compliant terminal emulation  
  2  Competitive performance  
  3  Basic customizability -- fonts, bg colors, etc.  
  4  Richer windowing features -- multi-window, tabbing, panes  
  5  Native Platform Experiences (i.e. Mac Preference Panel)  
  6  Cross-platform libghostty for Embeddable Terminals  
  7  Windows Terminals (including PowerShell, Cmd, WSL)  
  N  Fancy features (to be expanded upon later)
