I got conclusion that edit summaries cause more harm than good in many communities, due to the phenomena I recognize in many Wikipedias of inciting or trolling comments instead constructive summaries (especially in the form of question) and therefore would like to cancel them from backend in my personal MediaWiki site (CSS or JavaScript are not an option for me in this case).
Is there a ready-to-use way to totally cancel these (or to at least limit some characters inside them or add warning not to ask questions if a questions as summary but to prefer talk page) directly from LocalSettings.php?
Thanks anyway for your time,
