It's kind of crazy how many properties there are... I've been working with CSS for a long time and have never heard of “margin-inline” either.
It does make it kind of useful to write one line centers instead of two, but at the expense of people kind of needing to learn about damn logical properties when they read your code/blog.
Also, in my experience they interact with Flexbox and CSS Grid in useful ways that sometimes the "logical" properties are much easier to reason with than the 4-property versions or the individual property versions.
