[Mediawiki-l] Disabling purge of recent changes

[a@kid]

I am using portions of the DynamicArticleList extension code on my  
wiki (1.6.6). In the documentation for the extension ( http:// 
meta.wikimedia.org/wiki/Dynamic_Article_List )the author suggests  
disabling the deletion of old entries from the recent changes table  
by modifying Article.php .

Could this have any negative side effects apart from any performance  
issues related to keeping a larger recent changes table?

thanks
