That could just be a convention that upstream takes to keep the dependency graph sane, and downstreams could play a little looser if they want.

I've been thinking about some sort of project-level initialization (`initMlirCore`, `initEnzyme`, etc.) that would list such promises, but have hard time seeing how it wouldn't end up `#include`ing every single dialect and interface. Which could be acceptable given that `lib/IR` is clear of this and we only need headers. Adding string identifiers for interfaces and having a string/string map hardcoded or generated from tablegen feels too stringly.
