Deprecation: #66905 - Deprecate uc->classicPageEditMode and editRegularContentFromId option

See forge#66905

Description

The BE-User uc option "classicPageEditMode" which was used prior to TYPO3 CMS 4.0 has been removed some time ago. The functionality editRegularContentFromId which was then triggered in EditDocumentController has been marked for deprecation.

Impact

Any direct calls using editRegularContentFromId via GET parameter or calling editRegularContentFromId() directly from a third-party extension will trigger a deprecation message.

Affected Installations

Any installation using third-party code to restore the old behaviour.

Migration

Remove calls to the functionality.
