One thing that makes this hard is Unicode & OpenType. Decent line breaking requires hyphenation which with complex shaping requires entire words to be re-shaped for each combination of possible hyphenation points if we want optimal breaks.

I think hyphenation is more of a hack that good line breaking can generally avoid.

You need more than that. Find a typical LaTeX document and compile with and without \usepackage{microtype}. The difference is enormous. You need character expansion (small expansion to the characters themselves) to do it.
