While we are promoting the parsoid crate, it is still limited in various ways, like not working on unbalanced content or nested template content (T349520). mwparserfromhell has demonstrated that a non-perfect-but-good-enough wikitext parser still has immense value for bots, as we wait for Parsoid to gain support for more use cases (and content is rewritten to be more Parsoid friendly).

@Earwig has expressed interest in a mwparserfromhell port to Rust, but possibly with a different data structure/functionality.
