I'm on the fence as to whether this one should be on by default or not, since the QEC is not on by default.
Right, we shouldn't be adding [elevated]=false to all the docs by default, even when QEC isn't being used.
The only question left then is if the augmenter/transformer should be on by default if QEC is being used (i.e. forceElevation==true?) Or should the user explicitly put [elevated] in their field list? I'm thinking the latter, for folks who put fl=id and expect only the id field to be returned.
It would also be nice if one didn't have to define this EditorialMarkerFactory in solr.xml... seems like from the user perspective it should "just work" (either the QEC can dynamically register it, or it can always be registered by default like explain, docid, etc).
