As a new robotics company entering the ROS world, having clarity on this sort of point is very important to us. We’ve decided to go “all in” on ROS 2 only. Anything that we need from ROS 1 that is not being actively ported already is something that we will look at helping with going forward (time and budgets allowing.)
BTW, we are targeting our first “ROS” enabled release for the second half of 2019.
