When the text of a link is changed in VisualEditor, the link target does not change. This results in many, many edits which are entirely well-intentioned but for a patroller look like vandalism. E.g. a user tries to fix the wrong date [] and ends up with [[2000|2001]] - an erroneous link that is basically impossible to catch in visual view. (Some examples: diff, diff) This is a major problem; even highly experienced users fall prey to this, and new editors all the more (and then they get treated as vandals by the patrollers who are not familiar with VE and have no idea what's going on).
Maybe there could be some sort of notice asking whether the editor also wants to correct the actual target in case they change the displayed part of a wikilink (T55973#2792012 has a nice mockup).
