NASA tracks debris 10cm or larger. They also detect and statistically estimate debris as small as 3mm in LEO.

This is my source, from 2021 fwiw: https://oig.nasa.gov/office-of-inspector-general-oig/ig-21-0...

10cm is huge, that could even be a functioning 1U cubesat.

So it looks to be just the latency improvement that's noteworthy, then. Thank you!
