hi

Opam's .install files should be used only to fix packages whose
installation is already broken or unsufficient, shouldn't it?

If you rely *only* on the .install, your package can be installed only with
opam, it will break for other users (GODI, WODI, Manual Package
Management™, etc.).
I think it's good hygiene to at least provide an ocamlfind-based
installation of the libraries.
