The efficiency depends on the query size relative to the data distribution. A small query in a sparse region prunes almost everything. A query that covers the whole space prunes nothing (because every node overlaps), degenerating to a brute-force scan. The quadtree gives you the most benefit when your queries are spatially local, which is exactly the common case for map applications, game physics, and spatial databases.
A difficulty here, however, is that the TransformStreamDefaultController does not have a ready promise mechanism like Writers do; so the TransformStream implementation would need to implement a polling mechanism to periodically check when controller.desiredSize becomes positive again.
