Deprecation procedure for OCaml

In order to deprecate a feature from the OCaml system the following steps are taken:

1. Introduce a workaround for the deprecation (if needed). Document the workaround, see below.
2. When Debian stable has the version in which the workaround was introduced, start deprecating the feature with a visible warning
