This was apparently added 10 years ago to store metadata of UAVCAN components within the PX4 binary. The parameters in the xml are mostly early UAVCAN ESC parameters that are presumably out of date and not used. Also it does not scale to maintain metadata for all the possible UAVCAN components and it causes confusion when users read the metadata documentation because these parameters are not available in PX4. That's why I suggest to remove it.
- implement COMP_METADATA_TYPE_VERSION & add component_version.json.gz to
ROMFS for all targets.
- implement COMP_METADATA_TYPE_PARAMETER (only enabled for SITL currently)
