I've seen much the same problems when trying to programatically construct a large number of objects using the (low-level) Python API. If this kind of optimization improves throughput of those APIs that would be a major enabler for work that I want to do.
Otherwise I'm side-tracked looking for relatively awkward SIMD-style programming (e.g. Geometry Nodes) as a workaround for "CRUD" operations being too slow. Can't be just me...
This kind of thing can help understand other bottlenecks in software like Blender as its users and developers get more ambitious as the software grows in capability.
Idealistically wouldn’t one like film makers to be able to work ‘in world’ decoupled from technical limitations?
