Adds type-checking and combinator layers that may slow regex execution compared to raw libraries like ocaml-re, as benchmarks compare it with Angstrom for HTTP parsing.

Requires learning a domain-specific language of combinators (e.g., '*>' and '<&>') instead of standard regex strings, which can be unfamiliar and increase initial development time.

Niche to OCaml with fewer community resources and tutorials compared to mainstream regex libraries, potentially making debugging and adoption harder for new users.
