I think that having a sitemap.xml is a best practice. A super fresh sitemap can help get your pages get indexed sooner. My sitemap.xml page keeps me focused on getting all of my content indexed. These days I have a custom script that updates my sitemap file daily. So there is no reason to not “keep up with” the sitemap. I don’t know why folks upload their sitemap into GWT. Seems like a better idea to have it in the root.
@Sgt_Kickaxe, what are you doing where your sitemap would impact your SQL database? Did you generating the sitemap.xml every time the page was loaded? I don’t get it unless your sitemap had a million or more entries.
IMO removing a sitemap will have zero impact on pages already in the index.
