Disabling Emojis and Reaction Buttons in Issues and Discussions

In order to reduce room for miscommunications and emotional debate instead of productive conversation, I want the conversational pages associated wih my repositories to contain only plain text, without any fancy markup; and although it is unreasonable to prevent commenters from using markdown, and in fact I often use various emphasis marks in my own comments, I do think that it is reasonable to request removal of the distracting and imprecise reaction buttons, and disable the automated replacement of colon-bracketed tokens with icons and unicode glyphs.

In my opinion this would add unnecessary complexity to GitHub.
