I know it's way past the deadline for proposing Dev Summit sessions, but Community Tech would love to present the results of the Community Wishlist Survey which just concluded:

A lot of the proposals will be of interest to various teams, and we would love to discuss how this survey can feed into other teams' roadmaps and priorities, as well as discussing the overall feasibility of some of the proposals.
Even an informal aftre-hours or lunch session would be great.
