Hi, 

Esri ArcGIS is one of the most used geospatial software in the world. 
They have the concept of a "Hosted Feature Service" (HFS) that acts as the single source of truth within the system. 
An HFS is a data store that can hold geospatial information like vectors. Basically, every system in the Esri ecosystem integrates with the HFS, so having data in HFS enables the system to use it in a variety of end-user-applications. Additionally, third party geospatial enterprise SaaS solutions like Trimble CityWorks also integrate seamlessly with ArcGIS HFS. 

Having a Fivetran connector to sync between Esri ArcGIS HFS and other Fivetran sources/destinations would enable hundreds of cool geospatial usecases. 

All the best,
Toby
