When editing the configuration of a website, if we change the configuration of available languages, the sitemaps which are not selected are deleted. But we are not alert of the deletion.

For example, you have a website with two available languages : french and english. You edit the configuration of the website and only select french. On save, it should be great to have an alert of english sitemap deletion like : "Warning! You have an english version of your website, it will be definitively deleted the english sitemap if you accept to save this configuration. (Continue/Cancel)".
