In #135, we implemented detection of homebrew in order to work around neovim potentially breaking on upgrades. We couldn't just fallback to $PATH because some linux distros offered ancient Neovim neovim versions unable to run Firenvim, which would have made debugging issues harder. Most distros now have something recent enough to run firenvim - so falling back to $PATH could be a good idea.
