For everyone interested, I made an experimental tree-sitter parser for OpenACC directives to provide a minimal (directive) syntax highlighting for Neovim: [GitHub - loicreynier/tree-sitter-openacc: OpenACC grammar for tree-sitter · GitHub](http://github.com/loicreynier/tree-sitter-openacc)

I chose to create an external parser rather than contribute to [`tree-sitter-fortran`](https://github.com/stadelmanma/tree-sitter-fortran) as the syntax highlighting could be used with parsers for different languages via injections.

This idea was briefly discussed in an issue on the latter’s repository: [Highlight openmp statements · Issue #164 · stadelmanma/tree-sitter-fortran · GitHub](https://github.com/stadelmanma/tree-sitter-fortran/issues/164)
