Hi, GeoCrumbs is an extension deployed in Wikimedia servers: https://www.mediawiki.org/wiki/Extension:GeoCrumbs
It has no official maintainers, what about unofficial ones? Any volunteers? https://www.mediawiki.org/wiki/Developers/Maintainers
It also has one of the oldest code contributions waiting to be reviewed by anybody other than Jenkins. https://gerrit.wikimedia.org/r/#/c/65285/
Because of this change, GeoCrumbs currently leads the list of slowest projects reviewing patches. http://korma.wmflabs.org/browser/gerrit_review_queue.html
