1. So the SFUs we're currently looking at are yours, ion-sfu (and/or galene) and mediasoup. Honestly we haven't finished looking at how they compare for rate control, but the Pion team seems very interested in ensuring they have good rate control.

2. From context I think you're talking about noise cancellation here? I assumed that some of the more exotic ML-based ones ran serverside, which obviously is incompatible with E2EE. It sounds like there are a bunch of options for running WASM-based intelligent noise cancellation clientside though, especially with MediaStreamTrackProcessor and friends. rnnoiseless as a pure Rust->WASM port of rnnoise looks fun, for instance: https://github.com/jneem/nnnoiseless

3. True, although given Google are highly motivated to make AEC work properly in WebRTC, I guess I'm hoping that they'll continue improving it, much as they have been. I certainly never want to have to write or integrate one ever again :D
