Feedback on Beta Feature in Java Driver

Hello! In v4.9 of the Java Driver, we introduced a beta of Builders for Aggregation Expressions. The driver has had Builders for some time – Filters, Projections, Sorts, etc. – but this feature in particular is intended to introduce an idiomatic way to use the MongoDB Query API in Java.

Given that the feature has been in beta for some time, I’m curious to know if folks have tried it out and what they think (and if you haven’t tried it out, we have a tutorial here in the Developer Center!). All feedback is welcome, whether it’s positive or constructive, as it’ll be used to inform where we take the feature next. Please share feedback in this thread. Thank you for building with MongoDB!
