The original asker asked, "Will iTerm2 support ligatures at some point in the future?", so it was indeed a helpful answer to know that it does support ligatures.
I mean, within the context of this thread, it's pretty obvious the original question is asking whether ligatures would be supported in the Metal renderer, since it's explicitly listed as something not supported in the article, and since the asker is asking for the "feature roadmap for this".
