Having used both Jitsi and LiveKit, I get it. Jitsi is great if you use it as it is, but if you want to integrate video conferencing into your own solution and customize everything, LiveKit is the logical choice. (I think it is also much newer then Jitsi, which used to be the only choice.)

If they wanted to integrate a finished product, I would expect them to use Matrix over Jitsi, because it seems to have seen some use in France already.

Also, I think Matrix integrated LiveKit for video over their existing Jitsi integration, so... the ecosystem seems to flock around LiveKit anyway. So maybe the'll contribute to LiveKit if they find issues with it, and everyone benefits from that.
