Status: Ideas from this thread: https://devtalk.blender.org/t/render-engine-add-ons-performance/19251/7 to improve speed and ease for external render engines to work with Blender

Team
Commissioner: @brecht
Project leader: @BrianSavery
Project members: - Optional other developers, can be in multiple projects at once.

Description
Big picture: There are certain issues external renderers working with Blender have that Cycles does not due to it's access to the blender C data structures. Render Engine Addons have to work through the Python API and thus have limited performance. This "TODO" will include various subtasks for improving the render engine interface.

Use cases: Or possible things that could be improved

Faster reading of mesh vertices (as numpy array?)
Faster reading of hair or paritcles rather than using particle_system.co_hair(...)
Pre-load image data so that image.pixels.foreach_get() is not blocking. (see https://devtalk.blender.org/t/render-engine-add-ons-performance/19251/9)
Detecting deleted objects?

Branch: - Existing patches or branches.

Will confirm just to get this out of the Needs Triage status and this has @BrianSavery assigned.
Note that reading the devtalk thread, this does not mean it is officially confirmed to have core devs involved afaics.
