For this instance specifically (so not a proper solution): what about building it in a PPA / some other context and then setting up an import job @nuclearsandwich? Similar to how this is done for other packages (like Colcon, Gazebo and catkin_lint) in ros-infrastructure/reprepro-updater?
That’s probably what @smac was thinking of in his comment.
Would there be a way to donate cycles instead of money?
