This entire essay is just about how it should be "<scope> <optional type>" instead of "<type> <optional scope>"?

The essay gives a bunch of reasons to drop the "type" altogether and just use "<optional scope>" as prefix. The type either doesn't really mean anything or is redundant when writing commit headlines as English sentences. In a message like "Prevent thing from happening" the verb "prevent" is already basically a synonym for "fix". Similarly "Add" or "Support" likely implies "feat"/"feature".

To some extent the "type" is simply about trying to limit/standardize the number of possible "verbs" to start a commit headline with, in which case Conventional Commits made the mistake of mixing verbs and nouns (fix and refactor are verbs but feature and chore are nouns) and adding distracting punctuation where English prefers none between the Verb and its direct object in a "Verb the thing" sentence. "Verb: the thing" only ever really looks awkward.

But also do we really want to limit the possible number of verbs that a headline sentence can start with when making commits? "Fix" and "Prevent" may often act like synonyms but there are connotative differences. In some cases "Prevent" may be a shorter way to explain why something needed to be fixed in a headline because "prevent" also says "stop a thing from happening that wasn't supposed to happen" whereas "fix" alone may not yield that extra context. The top line of a commit should be a short and sweet headline and sometimes the cleanest way to do that is to use the full gamut of English verbs at your disposal to tell the right story as quickly as possible.
