Currently the data in Wikipedia section links is being dumped from functional accessibility in the database.
(In theory it could be accessed by searching all edits to an Entity.)
Dumping data that Editors have carefully selected as useful seems to reduce the power of MB. And be a strange direction for MB to be heading in.
One idea is to have the WPsection links transfered automagically to the Annotations.
Are there better ways forward?
(It may also be worth considering how better to respond to any future changes in what external links are acceptable.)
