No, not even close. There is more that doesn't work than works. Of what I use, all I got was python3 and git. But no python3.8, no ffmpeg, no erlang, no gnutls, and on and on.
ffmpeg has so many configure options, I always avoid building it with brew.
And for what I do, the default ffmpeg in Homebrew works fine.
There's something really offensive about apple being too cheap to just pay some homebrew devs. And dumping the work of the arch swap onto charity effort.
