If that's the only reason for maintaining OCaml ports, I'd rather remove all ports without any end-user reverse-depends. If we don't add oasis, this would be all devel/ocaml-* ports (for starters). Our current set of OCaml end-user applications has a quite modest set of dependencies.

In general I'd rather improve the quality of upstream / the OPAM repository than just OpenBSD ports. > There is enough metadata available in an OPAM package to generate a > snapshot of OpenBSD ports from a given package set.

Great! That's something I wanted for quite some time now, but I didn't know enough of OPAM to tell whether it was feasible.
