We often have a need to import existing content into wikis, for example from Google Docs or GMail. Most of those documents contain links, which are important for the semantics of the document.
Currently, VisualEditor strips all links unconditionally. It would be useful if it could offer users the option to instead preserve links.
One implementation option I could see work is as a pop-up triggered when detecting links, and with appropriate guidance on project policies on external linking.
