Benjamin Vedder was actually at the event. He spent some time helping people get builds configured properly and trying to sort out some bugs. Its always great to see developers actively engaged with the community and it must have been motivating for him to see the results of the work that hes doing.
Quietly hiding in his little box of dev tools was a VESC BMS. If hes working on a VESC BMS that can be linked to the can bus and controlled by the VESC software this has the potential to make huge safety improvements in many builds. Additionally it could be interesting for trampa prebuilts as currently most of there boards use LiPo packs which need an external balance charger.
