Okay, I haven't known there isn't a way to run this script locally. I updated the PR so that the dbgsym packages are not counted in the totals and are merged to the line with their base package:

Added Packages [16]:
 * ros-noetic-chaplus-ros: 2.1.26-1
 * ros-noetic-cras-imu-tools: 1.0.1-1 (+debug symbols ros-noetic-cras-imu-tools-dbgsym)

As the debug packages can be (in theory) added/removed independently of their base packages, I tried to reflect their added/updated/removed state by using +debug symbols, debug symbols and -debug symbols. I'm not sure whether this is worth it, though.
