@gvdhoorn, correct me if I'm wrong, but I think this repository is more focused on cross-compiling on Yocto (mostly arm64/aarch64), rather than focusing on compiling for another Linux distro. Also, I do actually need the ROS2 Foxy for Buster .debs for compiling my own ROS2 packages for Debian Buster, otherwise dpkg-buildpackage can't find the dependencies.
