Big Sur and fontconfig

I’m trying to install fontconfig on Intel Mac Big Sur. The install fails whether building from source or when forcing bottle. Message for forced bottle installation is below. Are there plans to support fontconfig on Big Sur or is this being impacted?

% brew install --force-bottle fontconfig

Do not report this issue to Homebrew/brew or Homebrew/core!

We don’t support Big Sur yet, but when we do all formula will be supported on it.

Thanks, Sean. I believe from the issues in GitHub that fontconfig is widely used and the patch works on Big Sur. So assume that is outdated info at this point in time.
