Unicode needed to include written-on-paper glyphs that existed in the world. That makes sense to most people. But a lot, lot, lot of communication these days happen digitally (digital first). You can't scribble things as freely in a textbox like this one. You can certainly make suggestive combinations like `:)`, but you are pretty limited. (How do you scribble "family of three: mom, father, daughter" without any emojis?)
How do you propose that Unicode include glyph innovations that are digital-first?
