I like how easy it was to implement into our API, we were able to use all of its features with very little configuration time or effort required by myself as an engineer at my previous employer (where they also used this for their own product).
The documentation could be improved but that's probably just because there isn't much out yet so things are still being worked through internally before more public release/documentation comes about later down the road once everything has been ironed out - which seems pretty standard from what i've seen around other products within tech companies I'm familiar w/. This definitely solved some problems when implementing custom endpoints where previously you'd have had trouble getting data back without having multiple nested APIs setup across different microservices / applications since each one would need unique fields etc., now those same tables can share similar schemas allowing us greater flexibility regarding future changes if needed while maintaining consistency.
