That piqued my curiosity. Could you please expand on this? What kind of hw accel can be applied to video when it is sent through DataChannels instead of the standard video channel?

The improvements in CPU usage are clear for the server, but the choice doesn't seem so obvious to me
EDIT: I meant that, for the quality of end-user experience (who doesn't care about server load), it doesn't seem like an immediately obvious better choice to just use GCM, until some empiric testing shows if the potential increase of packet loss causes noticeable problems, or on the contrary, doesn't. It would be very cool reading any observations in this regard.
You might see CPU improvements on the client side as well though! If you have a fixed set of clients it might be something worth evaluating.
I personally don't have any real-word deploys I can measure. The AES-GCM work came around because a Pion user mentioned it me, so then I added it/tried to push the issue in the IETF/W3C.
Somewhat tangentially related, for cases when P2P connectivity is not needed, there's also a proposal that lets you send data unreliably, but in a client-server setting: https://github.com/WICG/web-transport/blob/master/explainer....
Both are currently being actively prototyped in Chromium (full disclosure: I've been working on the latter).
