Are annotation files still in use?

I am checking the Vim OCaml support, and found that it still uses the types from *.annot files. Are they still in use, or this thing can be completely dropped for the next release of Vim and NeoVim?

See https://github.com/vim/vim/blob/master/runtime/ftplugin/ocaml.vim#L211 for more context

There are plans to deprecate them, but it has not yet been done. See https://github.com/ocaml/ocaml/pull/2141
