Basically, yes 
Drawcalls are minimal.

I hope you’ll like it too - Outline for GLB thin instances - Thin Instance Outline Gallery
The outline renderer uses one compact thin-instance draw per attached host and stores only highlighted IDs. Use createThinInstanceOutliner for ordinary meshes or raw Babylon Lite thin-instance indices. A host with a live Babylon Lite skeleton automatically shares its joint/weight streams with the outline and mirrors current bone matrices each frame.
The original idea for this outline feature came from increasinglyHuman/babylon-thin-instance-outline for Babylon.js. This package implements the approach natively for Babylon Lite and adds its own stable-ID, compact-pool, and live-skeleton workflows.

Very very cool!
I wish I could switch entirely to WebGPU/Babylon Lite with my Digital Twin implementation, but support on iPhones requires the newest MacOS 26 (not just an updated browser) so unfortunately this would not happen anytime soon.
