Per T358560 we want to deprecate BodyValidator and everything associated with it soon, ideally in MW 1.43.
Per the stable interface policy we should help third parties to replace their usage of the deprecated code.
For each of the extensions, we should propose a patch or file a ticket in the appropriate location.

This task is considered complete when a reasonable patch is proposed for each extension. It is not necessary to wait for these patches to be merged, especially if there are test failures unrelated to the change.
