It's been mentioned a couple of times in this thread, but Bevy also has an implementation of Nanite's ideas (sometimes called Virtual Geometry). I'm the author of that, happy to answer questions :) As for this project, Scthe did a great job! I've been talking with them about several parts of the process, culminating in some improvements to Bevy's code based on their experience (https://github.com/bevyengine/bevy/pull/15023 https://github.com/bevyengine/bevy/pull/15023). Always happy to see more people working on this, Nanite has a ton of cool ideas.
