The article would have been a lot better if there was at least one example of where a coding ligature was a problem, rather than talking about feet and inches

For instance it mentions the pairing => but provides no examples.

After reading I’m far from convinced that carefully curated language specific ligatures are a bad idea.

That's why e.g. Iosevka has language-specific ligations so you can chose between the standard, the slightly extended ML ligatures and the whole set of Coq craziness.
