To increase the usage of products developed by the interactive team a roadmap and quarterly timeline are being worked on within the team. Once this roadmap is decided and published it will provide a clearer path forward to support the team with this goal.
That said, the enabling of the <maplink> feature across Wikimedia projects and the presence of <mapframe> on a few Wikipedias has increased the tile usage.

On Wikimedia Commons alone we have seen maplink inclusion in 3.7 million file descriptions, up from 35k before its inclusion.
