- Almost certainly. In fact, there is already a submitted PR contribution for larger dimensions.

- C is much better integrated into Postgres, doesn't require pgrx. Given also experience developing pg_textsearch, and the acceleration from AI-assisted development and testing, have moved back to more C with extensions.

- Two reasons. First, decision to move back to C. Second, if there ultimately isn't much code overlap, better to keep them separate for easier adoption (smaller footprint and security/correctness envelop)
