Here's an example: in the first display,
\right are used throughout, while in the second several manual adjustments have been made in order to properly typeset the formulas.
I have no doubt whatsoever that the second version is better: it's more readable and less distracting. Yes, it requires some labor, but let me remind what τέχνη (techne) means:
τέχν-η , ἡ, (τέκτων)
A. art, skill, cunning of hand, esp. in metalworking, Od.3.433, 6.234, 11.614; also of a shipwright, Il.3.61; of a soothsayer, A.Ag.249 (pl., lyr.), Eu.17, S.OT389, etc.; “τέχναι ἑτέρων ἕτεραι” Pi.N.1.25; “ὤπασε τ. πᾶσαν” Id.O.7.50.
2. craft, cunning, in bad sense, δολίη τ. Od.4.455, Hes.Th.160: pl., arts, wiles, Od.8.327.332, Hes.Th.496,929; “δολίαις τέχναισι χρησάμενος” Pi.N.4.58; τέχναις τινός by his arts (or simply by his agency), Id.O.9.52, P.3.11; τέχνην κακὴν ἔχει he has a bad trick, Hes.Th.770, cf. Pi.I.4(3).35(53), S Ph.88, etc.
3. way, manner, or means whereby a thing is gained, without any definite sense of art or craft, μηδεμιῇ τ. in no wise, Hdt.1.112; ἰθέῃ τ. straightway, Id.9.57; πάσῃ τ. by all means, Ar.Nu.1323, Th.65, Ec.366; παντοίᾳ τ. S.Aj.752, etc.; “οὐκ ἀποστήσομαι . . οὔτε τ. οὔτε μηχανῇ οὐδεμιᾷ” IG12.39.22; “πάσῃ τ. καὶ μηχανῇ” X.An.4.5.16; “μήτε τ. μήτε μηχανῇ μηδεμιᾷ” Lys.13.95.

Typography is not just laying down letters, but it's also a craft and, in some cases (not this one, of course), art. As such we can't think that any automated system will be able to avoid human judgment.
TeX allows automation, with a not so bad output; if we want our documents to be good, we have to work on them. A good document is not to be hanged on museums' walls, but read by people: the less distractions, the easier will be reading it.
