The deprecation of Intel support is agressive! Every Mac enthusiast I know who uses a Mac as a server uses their old machines, which are pretty much all Intel. We'll lose support from you guys a year before Apple!
I know supporting Intel is an ordeal and a choice, but I'm firmly on the camp that Homebrew should find a way to maintain Intel support as long as possible.
If anything, the overwhelming majority of Apple enthusiasts have gone all-in on Apple Silicon. I sincerely doubt those using old Macs as servers are anything but a rounding error.
Yeah they also removed support for --no-quarantine flag :/ I only use it for a few casks nowadays and try to avoid Homebrew as much as possible. For CLI stuff I use Nix, Home-Manager and Nix-Darwin.
