That ship sailed long before Unicode. Even ASCII has characters with multiple valid glyphs (lower case a can lose the ascender, and lower case g is similarly variable in the number of loops), not to mention multiple characters that are often represented with the same glyph (lower case l, upper case I, digit 1).
That's a font issue with some fonts, not a green light for blessing multiple code points with the exact same glyph.
In fact, having a font that makes l I and 1 indistinguishable is plenty of good reason to NOT make this a requirement.
