Here are my 2 cents as a relative newcomer.
I started using ocamlformat from the very beginning, as I wanted to try the idea of “one style to rule them all”. Previously I always disagreed. Now I do agree that we need one style, but I very much disagree with the current ocamlformat style, although I still use it.
I wholeheartedly agree with the common theme in this topic.
The only way I can produce ocamlformat's style is by using ocamlformat. I write it in some other (much closer to what most people here propose) style and then run ocamlformat.
