Context:

I found WikiPage methods that used only with deprecated logic, while I was working with https://phabricator.wikimedia.org/T239975

I recommend:

• to research the usage of these methods
• to reengineering calls with actual logic
• to hard deprecate these methods
• to remove these methods in 1.36

Goal:

• to improve WikiPage/Article
• to minimize public methods and codebase of these classes

Methods for reengenering:

• \WikiPage::lockAndGetLatest - Has only one external usage PageUpdater::doModify with todo to replace
• \WikiPage::getUndoContent - Internal logic is deprecated with note: use RevisionSlotsUpdate instead
• \WikiPage::prepareContentForEdit - deprecated since 1.32, use getDerivedDataUpdater instead.
