Yes, and dropping Catalina means Zig disregards a lot of not really that old and still powerful Apple hardware, except what on this list:

  iMac (Mid 2014 or later)
  iMac Pro
  MacBook (Early 2015 or later)
  MacBook Air (Mid 2013 or later)
  MacBook Pro (Late 2013 or later)
  Mac Mini (Late 2014 or later)
  Mac Pro (Late 2013 or later)

And by similarity of supporting last 3 macOS release, this will grow to hardware of ~2016 if they drop support of Big Sur next.
