It's hard enough to find a good coding font without having to disqualify them because of their ligatures. Many fonts overdo it with making them pretty or look like single characters. If they instead appeared like two typed characters that form a single operator without much ambiguity that could be useful. Of course you don't want to depend on using the ligatures for the whitespacing to be 'right'. Much as colored syntax can go very wrong with a poor color palette, mappings, or monitor color profile, ligatures go wrong enough not to make it worthwhile. Maybe they'll get sorted out eventually as we have good color defaults these days.
