Is uploadBlob the right way to share large binary (300+ MB) in Fluid 2.x, and why is it marked @legacy, or is there a better way?

[devdeeprc]

We have a static web app that shares large binary data (300+ MB .glb models) across participants in a Teams call via Fluid Framework. What's the recommended way to do this in the latest framework?

The approach I'm leaning toward is uploading the data with uploadBlob (https://fluidframework.com/docs/api/datastore/fluiddatastoreruntime-class#uploadblob-method) and sharing the returned handle with other participants via a SharedTree.

My question is about its status: uploadBlob is marked @legacy in the current docs. Does that mean the API will be removed in the future (and is a replacement planned), or does it mean there's already a better/recommended way to share large binary that I should use instead?
