I'm not sure I understand the "mess" part. Can you show an example of what such "messing" produces in the simple recipe I suggested above? Also, I'm guessing those vendors don't touch the Windows builds, do they? > Perhaps we need a `harfbuzz-available-p` defun? We could add that if there's a reason good enough. The advantage of what I proposed is that it also detects the cases where HarfBuzz is available, but for some reason not used.
