IMO, we already have too many view types.  But I don't think we can necessarily
combine this with any existing ones.  Could we at least make it cover something
more broad, so that if we ever do hosting of extension content again, we don't
have to add yet another?

Done (s/EXTENSION_OPTIONS/EXTENSION_GUEST/).
Should we then also add VIEW_TYPE_EXTENSION_GUEST to <appview> and
<extensionview> ?
