Big long rant trying to very weakly justify a personal preference that you can easily enable/disable if you want, and which is strictly visual anyway. They do almost never go wrong, meaning if you find it makes your code easier to read and more pleasant to look at, this is well worth the essentially negligible number of times they cause an issue. And you can just disable / not use the ligatures in those cases!
