Remove neo4j inactive labels from database

What is the method for removing inactive, unwanted node labels in a Neo4j database (community edition version 2.2.2)?

I've seen this question in the past but for whatever reason it gets many interpretations, such as clearing browser cache, etc.

I am referring here to labels actually contained in the database, such that the REST command 

GET /db/data/labels

will produce them in its output. The labels have been removed from any nodes and there are not active constraints attached to them.

I am aware this question has been asked in the past and there is a cumbersome way of solving it, which is basically, dump and reload the database. The dump command doesn't even contain scattered commit statements and thus needs to be edited before executing it back. Of course this takes forever with big databases. There has to be a better way, or at least there is a feature in the queue of requirements waiting to be implemented. Can someone clarify?

If you delete the last node with a certain label - as you've observed - the label itself does not get deleted. As of today there is no way to delete a label.

However you can copy over the datastore in offline mode using e.g. Michael's store copy tool to achieve this.

The new store is then aware of only those labels which actually are used.
