graphql_ppx currently uses ppx_tools_versioned, which is slowly rotting, instead of the now-standard ppxlib. In turn, this means we need ocaml-migrate-parsetree, which blocks ant upgrade of ppxlib, itself needed for OCaml upgrades (see #10940).

The latest upstream versions of graphql_ppx use ppxlib, but are targeted at Reason instead of OCaml, so we cannot use them.

Two alternatives:

  • find an upstream version which still targets OCaml and uses ppxlib, if it exists
  • re-engineer the current custom graphql_ppx so it uses latest ppxlib

Actually the latest version of graphql_ppx can be used perfectly with OCaml. The reason it has not been upgraded thus far is that is was rewritten in ReasonML. However recently everything has been rewritten back to OCaml, so we should consider using latest upstream graphql_ppx.
