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 only Apple put a fraction of its resources towards maintaining something like homebrew (or paying the people who do), maybe the situation would be different.
