U+07E6 probably should be rendered as exactly like “SS” (not a ligature, and as a double-width character in monospace fonts). Inventing a separate glyph for it

U+07E6 probably should be rendered as exactly like “SS” (not a ligature, and as a double-width character in monospace fonts). Inventing a separate glyph for it seems a bit silly and only hinders adoption. Even if it's a ligature like §, that issue won't go away. And there are design choices that are even worse than § due to historic precedent.
