[ros-users] [Discourse.ros.org] [Next Generation ROS] Relaxing ROS2 topic/service field name restrictions

[Chris]

Back in 2015, the ROS2 rules for the names of fields in topic and services were tightened up to disallow uppercase characters (and hence camel case).  The original discussion seems to have been here:

with the follow-up PR done here:

https://github.com/ros2/rosidl/pull/25

Since then, some users of ROS2 have expressed a desire to loosen these restrictions, and put the rules back to what they were in ROS1 (allowing camel case, among other things).  I'm interested in hearing opinions from the community on whether the restrictions are beneficial, harmful, or don't matter very much.  Thoughts welcome!
