   Thanks for the read Paul. The Intro was meant to convey the goals of the proposal, in priority order:
   
   > This proposal is designed to improve indexing throughput, reduce hot spots for write-intensive workloads, and offer a horizontally-scalable API for consumers to process the change capture feed for an individual database in CouchDB 4.0.
   
   That said, I totally spaced out on the `ebtree` data structure here; I was still thinking of the model where view KVs are stored as KVs directly in FDB. So yeah, this is spot-on:
   
   > We're still left with the fact that writes to the view ebtree aren't currently parallelizable. If we want to make view updates faster, the first thing I'd investigate is how to upgrade ebtree to allow update-in-place semantics with the MVCC semantics that FDB offers.
