-# If we have parallel copies of 2D datatypes every UI and other pipeline will end up needing to have dual interfaces to plot everything. And you will end up with not being able to use 3D tools for 2D use cases even if they're completely valid, as you'd have to reimplement it with different inputs and outputs. It's not particularly hard to plot the 2D pose or compute the yaw error for the Pose message and there are already tools and libraries that can do this for you.
