As mentioned above I am in favor of mapping byte[] In Python to bytes instead of a list of integers.

Currently, in Python, `byte[]` maps to a list of `builtin.bytes` (each list element being of length 1). And I agreed with you it could be just `builtin.bytes` and not a list.
My understanding is that the proposal from @Zongpei_Jiang is to map `uint8[]` to `builtin.bytes` as several ROS 1 messages use uint8[] to send binary data around. So this is a different proposal I think, and I'm not sure that this should map to `builtin.bytes` in that case.

Instead the existing mapping (see
http://design.ros2.org/articles/generated_interfaces_python.html) should be re-evaluated. In that process all other language mappings need to be considered too.

:+1: that's been on our list for a long time but we didn't get around doing it yet.
