Users have asked for a way to add a "remember me" checkbox to enable/disable the setting of the ext_id cookie. Mailing list thread: http://groups.google.com/group/liftweb/browse_frm/thread/82b931d4bf43d10a/473332fda485d038?lnk=gst
If there are code changes, I'd be willing to update the wiki page accordingly.
Additionally, in the UK next year, web sites will need to get permission before setting non-essential cookies, which we believe would include the extended session cookie.

Would this be in the ProtoUserExtendedSession stuff, or elsewhere?
Regarding my comment for the EU cookie stuff, I'm fine and don't need any changes.
Regarding the original request from @KenMcDonald, I believe that would be in relation to the ExtendedSessions documentation on the Wiki and is Mapper specific.
Other implementations (such as MongoAuth and MapperAuth) already implement this via isRemember, which might well be enough. Personally, I'm now handling things things more client-side and I don't need changes.
