SPAN vendor product manager is in favor for the repository change. This repository is many commits ahead of the upstream current default Span integration. I believe the upstream repository is abandoned as critical (crash) pull requests are not being processed for some time. The upstream does not allow writes from contributors. The subject of this pull request is now part of an Github organization with code owners/members who previously contributed fixes for previous forks, modulo the upstream personal repository owner who has not responded to his invite as of yet.
